(b) Description The moving ports group [ 3 ], which converts the recoil energy generated when firing a round into the kinetic energy necessary for the operation of the submachine gun, consists of the breech block assembly (420) which can slide back and forth along its guide rods (C2).

When a round is fired, the resulting recoil force causes the breech block assembly (420) to move rearwards, against the force of the return springs (477). Once the breech block assembly (420) has reached the breech block assembly stop block (4 74), it will be halted and then moved forwards under the force of the return springs (477). The rate-of-fire stabilizer (48 1) ensures an even movement of the breech block assembly (420) along its guide rods (C2).

2.2.3.

Moving parts group [ 3 ] (continued) (b) Description (continued) The breech block assembly (420) is compose d of the steel breech block (C 1) onto or into which the followi ng components have been installed : The firing pin (425) and its spring (423) which are held in place by the spring pin (437)

When, during the firing operation, the hammer (515) is released from its cocked position, it hits the rear extremity of the firing pin (425). The firing pin is then propelled forwards and hits the primer of the cartridge so that firing tokes place. After firing, the firing pin (425) returns to its initial (rear) position by the force of its spring (423). - The extractor spring (431) and the extractor (435) which are respectively held in place by the spring pin (433) and the spring pin (437)

The extractor (435), which lightly protrudes from the front face of the breech block (C1 ), is held in o spring-tensioned position by its spring (431). When, during the feeding operation of o cartridge from the magazine { 5 }, the front face of the breech block (C 1) pushes the cartridge into the chamber, the rim of the cartridge clicks itself into the extractor (435) (also refer to§ 3.3.3). The ejector (443) and its spring (441) which are held in place by the spiral pin (445) As the spiral pin (445) has been installed at on angle, the slot in the eiector (443) is oriented

accordingly. The eiector (443), which lightly protrudes from the front face of the breech block (C 7), is held in o spring-tensioned position by its spring (441 ). When, during the feeding operation of a cartridge from the magazine { 5 ], the front face of the breech block (CJ) pushes the cartridge into the chamber, the eiector (443) is completely pushed into the breech block. After the firing operation, when the moving ports start their rearward movement, pressure will be exerted by the eiector (443) on the top rear port of the cartridge case, causing the case to pivot around the extractor (435) : the case will disengage from the extractor (435) and leave the weapon through the eiection opening.

The guide assembly (4 70) consists of the 2 breech block assembly guide rods (C2) fitted, at the rear side, into the breech block assembly stop block (474) .

CHAPTER 3 : OPERATING PRINCIPLES 3.1.

-.

.

INTRODUCTION The operation of the P9Q® submachine gun depends on the setting of the fire selector (255) . The fire selector (255) can be set at one of the following 3 positions : • The position 'S' (SAFE) : "safe mode" or "initial mode" (refer to § 3.2)

---

When the fire selector (255) is at this position, it is impossible to operate the trigger (26 J). The position 'S' should be selected in one of the following cases : - When the P9Q®submachine gun is not operational ("safe mode"). - When preparing the P9Q®submochine gun for operation in one of the two firing modes ("initial mode"). • The position ' 1' (sing le-shot) : "semi -automatic firing mode" (refer to § 3.3)

~.

When in this mode, the trigger (26 J) con be moved but its rearward movement is restricted. The P9Q®submachine gun fires semi-automatically : one shot will be fired for each trigger pull. • The position '1\ (ful l-automatic) :"full-automatic fi ring mode" (refer to§ 3.4)

When in this mode, the trigger (26 J) can be pulled completely rearwards. When the trigger (26 J) is pulled completely rearwards and held there, the P9Q®submachine gun will start firing a burst. If, in this mode, the trigger (26 7) is only pulled halfway rearwards, the P9Q®submochine gun will fire semi-automatically. If only one round is fired when pulling the trigger (26 7) rearwards, do not release the trigger pulling it all the way rearwards until the burst starts.

but continue

NOTES : - In both firing modes, the movement of the trigger (261) is transmitted via the operating rod (269) towards the hammer group [ 4 ]. The hammer group contains 4 sea rs (519, 53 1, 533 & 541) controlling the operation of the hammer (515) and, as a consequence, also the firing mode of the weapon (refer to the following paragraphs). - For a short description of the safety sear (5 41 ), which has been provided as a safety feature in order to ensure that the firi ng mechan ism is blocked if the loaded and cocked P9Q® submachine gun is accidentally dropped, refer to§ 3.5 .

3.2.

THE 11SAFE MODE11 I THE "INITIAL MODE" (Fig. 3.a) When the fire selector (255) is at the position 'S', it is impossible to operate the trigger (261) : the lug (L) provided on the rear part of the body of the fire selector is in with the rear, right portion of the trigger so that the trigger is blocked. There are 2 possibilities : •

The P90® submachine gun is not operational (carried in its carrying bag, stored, ... ) In such a case, it is recommended that the fire selector (255) is at the position 'S' .

•

The P90® submachine gun is being prepared for operation in one of the 2 firing modes For safety reasons, the fire selector (255) should always be set at the position 'S' when carrying out the following preparatory operations (the P90® submachine gun is in the socalled "initial mode") : - The installation of a loaded magazine [ 5 J onto the submachine gun - Cocking the gun by pulling the cocking handle (150) completely rearwards and then releasing it

When cocking the P90®submochine gun, its hammer (515) will be placed in the cocked position and the obturator assembly (83) of the eiection opening will be opened. If a loaded magazine [ 5 J has been installed onto the gun, a cartridge will also be fed into the chamber of the barrel ( 131).

NOTE : If the P90® submachine gun will not be used immediately after it has been cocked, the obturator assembly (B3) of the ejection opening can be closed manually.

This is especially useful in order to avoid the penetration of foreign particles in side the P90®when the weapon is carried in a dirty, sandy, ... environment. When the obturator assembly (83) has been closed, it will automatically be reopened by the following rearward movement of the breech block assembly (420) which will toke place during o next rearward pull of the cocking handle (150) or when the first round is fired.

Fig. 3.a shows a loaded P90® submachine gun in the "initial mode" after having carried out the preparatory operations : - The breech block assembly (420) is positioned at its most forward position and t he cartridge (C) is pushed into the chamber of the barrel (131 ).

When the breech block assembly (420) is positioned at its most forward position, it is said that "the breech is closed". - In its most forward position, the breech block assembly (420) releases the automatic sear (519) from the hammer (5 15).

The protruding port of the automatic sear (5 19) is actuated by the breech block assembly (420). In this mode, the hammer (515) is held in the cocked position by the rear sear (533).

The rear sear (533) engages the flat face of the rounded part of the hammer (515).

SEMI-AUTOMATIC FIRING MODE

3.3.1.

Firing the first round (Fig. 3 .b) • The fire selector (255) is set at the position ' 1' (single-shot).

As o result, the lug (L) provided on the reor port of the body of the fire selector (255) moves partly towards the left side, releases the rear; right portion of the trigger (261) and becomes aligned with the left portion of the trigger which does not protrude so far rearwards.

In the semi-automatic position, it is possible to pull the trigger (261 ), but its rearward movement is restricted. •

When the trigger (261) is pulled, its restricted rearward movement is transmitted via the operating rod (269) to the rear sear (533) of the hammer group [ 4 ] : the rear sear is pushed rearwards and, as a consequence, releases the hammer (5 15).

The rear sear (533) disengages from the flat face of the rounded part of the hammer (515). •

Under the force of its right and left springs (5 13) and (514), the hammer (515) is raised and hits the fi ring pin (425) wh ich is propelled forwards : percussion to kes place and the round is fired.

NOTE : An important safety feature of the P9Q® submachine gun is that firing is only possible with the breech closed (i.e. with the breech block assembly (420) positioned at its most forward position) even when the hammer (515) is cocked.

If the breech block assembly (420) is not positioned at its most forward position (the breech is not closed), the protruding port of the automatic seor (57 9) is not actuated by the breech block assembly. As a result, the automatic sear (5 19) remains subjected to the force of the front extremity of the left hammer spring (514) so that the seor will remain engaged into the groove of the cocked hammer (515) : the hammer remains blocked in its cocked position and firing is impossible.

3.3.2.

Rearward movement of the moving parts (fig. 3.c) When the round is fired, the recoil force of the cartridge case causes the breech block assembly {420) to be moved rea rwards, compressing the return springs {4 77) and causing the fol lowing operations to take place :

(a) Opening the obturator assembly (83) of the ejection opening This operation will only take place if the obturator assembly (83) has been closed manually. If the obturator assembly {B3) is closed, it wil l be reopened automatically by t he with the breech block assembly {420) during the rearward movement of the moving parts.

(b) Extraction and ejection of the empty cartridge case

--

At the beginning of the rearward movement of the moving parts, the extractor {435) still holds the (empty) cartridge case.

The case is held by its rim which has clicked itself into the extractor (435) during the feeding operation. As the rearward movement of the moving parts continues, pressure will be exerted by the ejector {443) on the top rear part of the cartridge case.

Before the rearward movement of the moving parts, the cartridge was pushed into the chamber of the barrel (13 1), causing the ejector (443) to be completely pushed in. The combined effects of the extractor {435) and the ejector {443) (being held bock at its bottom and being pushed at its top rea r part) cause the empty case to pivot around the extractor {435) : the case wil l disengage from the extractor (435) and leave the weapon through the ejection opening.

(c) Recocking the hammer (515) During its rearwa rd movement, the breech block assembly (420) comes into with the hammer (515) and pushes it, against the force of the right and left hammer springs (513) and {514), rearwards and downwards into the cocked position.

As long as the breech block assembly (420) has not returned towards its most forward position, the hammer (515) will be held in the cocked position by means of the automatic sear (519) which engages the groove provided in the hammer body.

If the trigger (261) is kept pressed after the shot, the rear sear (533) is positioned too for rearwards to be able to hold back the hammer (515) in the cocked position : the hammer will be held in the cocked position by the front sear (531 ). If the trigger (26 1) is now released, both the front and rear sears (53 1) and (533) return towards their initial, forward position. As a result, the front sear (531) releases the hammer (515) which is caught, and therefore held back in the cocked position, by the rear sear (533).

3.3.3.

Forward movement of the moving parts (Fig. 3.d) Once it has reac hed its most rearward position (determined by the breech block assembly stop block (474)), the breech block assembly (420) will be propelled bock forwards under the force of the return springs (477). During its forward movement, the breech block assembly (420) causes the following operations to toke place :

(a) Feeding a new cartridge from the magazine [ 5] - When the breech block assembly (420) is positioned at its rearward position, there is sufficient space between the chamber of th e barrel ( 131) and t he front face of the breech block to allow a next cartridge to be fed from the magazine [ 5].

The head of the magazine case (620) has been conceived so that the cartridges ore rotated from their /otero/ orientation in the magazine to the forward orientation required for the feeding operation. During the forward movement of the moving parts, the upper front part of the breech block will come into with the rear port of the cartridge so that the cartridge will be pushed out of the lips of the magazine case (620) and into the chamber of the barrel (131). - The breech block continues pushing the cartridge until it is completely fed into the chamber of the barrel (131) .

The end of this operation corresponds to the most forward position of the breech block assembly (420). At that moment, the rim of the cartridge cose clicks itself into the extractor (435). Also at that moment, the force exerted by the cartridge is so strong that the eiector (443) is pushed into the breech block.

(b) Releasing the automatic sear (519) Once the moving ports have reached their most forward position, the protruding part of t he automatic sear (5 19) is actuated by the breech block assembly (420) so that the sear is released from the groove in t he body of the hammer (515). The hammer (515) is now only held bock in the cocked position by the rear sear (533) and/or the front sear (531 ).

If the trigger (261) is kept pressed after the shot, the rear sear (533) is positioned too for rearwards to be able to hold bock the hammer (515) in the cocked position : the hammer wi/J be held in the cocked position by the front sear (531). If the trigger (261) is now released, both the front and rear sears (531) and (533) return towards their initial, forward position. As o result, the front sear (531) releases the hammer (515) which is caught, and therefore held bock in the cocked position, by the rear sear (533).

Once t he moving parts have reached their origina l position and the trigger (261) has been released, the P90® submachine gun is ready to fire a next single shot.

FULL-AUTOMATIC FIRING MODE • The fire selector (255) is set at the position

'PI (full-automatic).

As o result, the lug (L) provided on the rear port of the body of the fire selector (255) moves completely towards the left side, so that if is no longer aligned with any port of the trigger (261 ).

In the full-automatic position, it is possible to pull the trigger (261) completely rearwards. • When the trigger (261) is pulled completely rearwards, its movement is tra nsm itted via the operating rod (269) to the rear sear (533) of the hammer group [ 4 ] : the rear sear is pushed completely rearwards and, as a consequence, releases the hammer (5 15).

The rear sear (533) disengages from the flat face of the rounded part of the hammer (515). When the trigger (261) is pulled completely rearwards, the rear sear (533) moves towards its most rearward position where it becomes inoperative : the sear is no longer able to reengage the hammer (51 5) when the hammer is cocked during the rearward movement of the moving parts. When the rear sear (533) moves towards its most rearward position, the front sear (531) is pivoted forwards so that it also becomes inoperative.

•

Under the force of its right and left springs (513) and (514), the hammer (5 15) is raised and hits the firing pin (425) which is propelled forwards: percussion takes place and the first round is fired.

•

During its rearward movement, the breech block assembly (420) comes into with the hammer (515) and pushes it, against the force of the right and left hammer springs (513) and (514), rearwards and downwards into the cocked position.

As long as the breech block assembly (420) has not returned towards its most forward position, the hammer (515) will be held in the cocked position by means of the automatic sear (519) which engages the groove provided in the hammer body. As long as the trigger (26 1) is held completely rearwards, the rear sear (533) and the front sear (53 1) are inoperative (see above) so that the hammer is only held bock in its cocked position by the automatic sear (579) . • Once the moving ports have reached their most forward position, t he protruding part of t he automatic sear (51 9) is actuated by the breech block assembly (420) so that the sear is released from the groove in the hammer body : a new round is fired . • As long as the trigger (26 1) is held completely rearwards, the operation of the hammer (515) is on ly controlled by the automatic sear (519) and the firing operation is repeated : the submachine gun f ires full-automatically.

The firing will continue os long as the trigger is held fully rearwards and cartridges are present in the magazine [ 5].

NOTE : In t he full-automatic firing mode, single-shot firing is possible by only pu lling the trigger halfway rearwards.

The criterion for full-automatic firing is that the trigger should be pulled so for rearwards that the rear sear (533) and the front sear (531) become inoperative.

SAFETY SEAR (541) When a loaded and cocked P9Q® submochine gun is accidentally dropped on its f lash-hider, the force of inertia when ing the ground causes the safety sear (54 1), which is a part of the hammer group [ 4 ], to pivot forwards against the force of its spri ng (545). Whatever the position of the fire selector (255), the pivoting movement of the safety sear (54 1) causes the rear sear (533) to be blocked so that it cannot move rearwards. As a rearward movement of the rear sear (533) is required to release the ha mmer (515) and initiate o firing operation, on occidental firing is impossible .

3.6.

VISIBLE AND INFRA-RED LASER (only P9Q® LV, P9Q® LIR, P9Q®TR LV and P9Q® TR LIR) NOTE : The power requi red for the operation of the visible or infra-red laser, is supplied by a lithium 3 V type 2/3A battery which fits into its holder provided in the rear grip of the submochine gun, just behind the "laser ON" button .

.The operation of the visible or infra -red laser depends on the setting of the laser selector (B4) . The loser selector (B4) can be set at one of th e following 3 positions (Fig 3.D : • The centre position (0) : "no-power position" When the loser selector (84) is at this position, the laser will not function when the "laser ON" buffon is pressed. The "no-power position" should be selected when the P9Q® submachine gun is not operational or when the use of the loser is not required.

• The front position (I) : "low-power position" When the loser selector (84) is at this position, the loser will operate at reduced power (0. 95 mW) when the "laser ON" buffon is pressed. The "low-power position" should be used for training in order to reduce the risk of damaging the eyes and to ensure that the boffery lasts longer.

•

The rea r position (I I) : "full-power position" When the loser selector (84) is at this position, the laser will operate at full power (5 mW) when the "loser ON" buffon is pressed. The "full-power position" should only be used in combat situations.

TRITIUM LIGHT SOURCE (714) (only P90®, P9Q®LV and P9Q®LIR) Ensure to be familiar with the following instructions before any intervention on the optical sight (711) which contains the tritium light source (7 14):

General information concerning the tritium light source (714) •

The trit ium light source, incorporated in the optica l sight (711 ), consists of a completely sea led g loss capsule internally coated with phosphor and containing the radioactive gas tritium (hydrogen-3). The triti um has an isotopic purity of at least 94% and emits only 6 particles having a maximum energy of 18.4 keV

•

The correctly sealed tritium light source presents no external radiation hazard.

• A defective tritiu m light source cannot be repai red !

Handling the tritium light source (714) • Th e optical sight (711) has been designed to withstand normal operational conditions without any risk of da mage to th e incorporated tritium light source. It is nevertheless recommended to handle the sight with care .

• If t he triti um light source should be replaced, th is replacement should be carried out in a well-ventilated, NO SMOKING and NO EA"ING AN D DRIN KING area.

Storage of spare tritium light sources (714) Spare tritium light sources should be stored under normal ambient conditions in a wellventilated designated storeroom .

Breakage of a tritium light source (714) •

In th e event of an (accidenta l) breakage of a trit ium light source, tritium gas might be released into the atmosphere (where it will be rapidly diffused) or, if the light source is st ill assembled in the sight, into the silico ne rubber surround . In an y case, any risk of internal radiation of personnel can be minimized by fol lowing the followi ng procedu re : - Inform the other people present in the room. - Evacuate the room for at least 15 minutes. Fully venti late the room after returning and then, without touching them directly with the fingers, put the broken fragments of the tritium light source as well as the su rrounding sil icone rubber in a plastic bag The plastic bag should then be disposed of as radioactive waste.

•

In the event of a simultaneous breakage of many triti um light sources, proceed as explained above but inform the competent local authorities before retu rning into the room.

Disposal of a tritium light source (714) Old or defective tritium light sources should be d isposed as radioactive waste. Information about the disposa l of this kind of waste ca n be obtai ned from the competent local authorities.

• If the

• Load the cartridges, o ne by one, into the magazine [ 5 ] by proceeding as follows (Fig. 6.b) : - Hold the magazine [ 5

I by its rounded end and with its lips facing upwards.

- Place the cartridge with its rear pa rt o n the wider part of th e lips of the magazine.

Ensure that the bullet points forwards, along the magazine body (620). - With the th umb, push the cartridge downwards and then rearwards until it locks into position. The transparent magazine body (620) allows you to estimate t he number of cartrid ges present in the magazin e [ 5 I which has a capacity of SO cartridges.

6.2.

LOADING AND COCKING THE SUBMACHINE GUN It is assumed that the chamber of the submachine gun is empty, that no magazine has been installed onto the gun and that the gun has not been cocked.

• Set the fire selector (255) at the position 'S' (SAFE) (Fig. 6.c). • Install a loaded magazine [ 5

I onto the submachine gun (Fig. 6.d).

In order to ensure that the magazine { 5] correctly locks into position, push firmly on its rear part (check if the magazine is correctly locked into position by pulling it upwards). •

Pull t he cocking hand le (l 50) completely rearwards and then release it (Fig. 6.e).

This causes the hammer (5 15) to be cocked, the first cartridge to be loaded into the chamber and the obturator assembly (83) of the eiection opening to be opened.

NOTE : If the P90® submachine gun will not be used immediately after it has been cocked, the obturator assembly (83) of the ejection opening can be closed manua lly.

This is especially useful in order to avoid the penetration of foreign particles inside the P909 when the weapon is carried in a dirty, sandy, ... environment. When the obturator assembly (83) has been closed, it will automatically be reopened by the following rearward movement of the breech block assembly (420) which will take place during a next rearward pull of the cocking handle (150) or when the first round is fired.

CHAPTER 8 : MAINTENANCE Before any intervention on the P90® submachine gun, ensure to be fa miliar with the safety information given in chapter 4 of this Maintenance Manual.

The frequency at which the P90® su bmachine gun should be cleaned and lubricated depends on the ammunition used, the weather and shooting conditions and other external factors. When using normal ammunition under normal conditions, it is a good rule to clean and lubricate the submachine gun after every use or, in case of inten sive shooting, after each 2000 rounds : correct maintena nce will enhance the longevity of the gun.

NOTE : When using subsonic ammunition, which results in a much quicker soiling of a weapon, the cleaning frequency should be conside rably increased : the condition of the submach ine gun should be followed up all along the shooting seq uence.

Before cleaning the P90® submachine gun, ALWAYS ensure that it is unloaded (refer to§ 6.4).

8.2.

CLEANING AND LUBRICATION BEFORE FIRING The following procedure assumes thot the P9Q®submochine gun has correctly been cleaned and lubricated the lost time it has been used (also refer to§ 8.3). If the P9Q® submochine gun is used for the first time upon purchase, it is assumed that the procedure described in chapter 5 hos been carried out. • Carry out the field stripping procedure (refer to chapte r 7). •

Using the cleaning tools OREA 85 1 and clean rags (pieces of flannel), remove the maintenance lubricant from the inside of the barrel (131) until the lost rag is clean .

•

Dry the inside of the barrel ( 13 1).

• Rem ove the maintenance lubricant from the moving parts group [ 3]. • Slightly lubricate the moving parts group [ 3 ] by proceeding as follows : - Apply 2 drops of functional lubricant to each breech block assembly guide rod (C2), just behind the breech block assembly (4 20) . - Move the breech block assembly (420) at least three times back and forth. Apply 1 drop of f unctional lu bri ca nt to the ejector (443), to the extractor (435) and to the ho les of the breech block assembly (420).

The other ports of the submochine gun do not require lubrication. • Reassemble the gu n.

The P90® submochine gun o nly requires minimal lubrication. Excessive lubrication of the weapon or the presence of a lubricant inside the magazine [ 5 ] will have on unfavourable effect on the rel iabil ity of the weapon and the longevity of its parts.

Before each shooting sequence, A LWAYS check the barrel ( 131) for obstructions and ensure that it is dry and clean.

The automatic sear (57 9) should be oriented so that its protruding part is at the left upper side. When fitting the automatic sear (57 9) into the hammer group body (57 7), the slot (v) in its left bottom part should fit onto the free extremity of the left hammer spring (57 4). W hile compressing the left hammer spring (514), align the hole in the automatic sea r (519) with the hole for the parallel pin (551) (1) in the right side of the hammer group body (511) and then, from the right side, insert the drift punch UT 2001 throug h the 2 holes, just enough to temporarily secure the automatic sear (519) into position. - While acting on the drift punch UT 2001 in order to correctly position the hole in the automatic sear (519), insert, from the left side, the parallel pin (55 1) (1) into the corresponding hole in the left side of the hammer group body (5 11 ). - Using the hammer UT 211 0, drive the parallel pin (551) (1) ful ly home, allowing it to push out the drift punch UT 2001.

The parallel pin should through the hole in the automatic sear (519) and then fit into the hole in the right side of the hammer group body (51 7). When carrying out the following checking procedure, be careful not to trap your fingers !

After having reassembled the hammer group [ 4 ] ond before reinserting it into the submachine gun, check if it operates correctly by proceeding as follows (Fig. 9 .5.o) :

If one of the following checks does not give the expected result, check if the hammer group [ 4 ] has correctly been reassembled. •

Ensure that the hammer (515) is in the decocked position (part A of fig. 9 .5.o) and then push it into its cocked position (part B of Fig. 9.5.o).

When pushing the hammer (57 5) into its cocked position, the rear sear (533) will first be moved rearwards by the rounded port of the hammer. When the flat face of the rounded part of the hammer (57 5) reaches the opening in the rear sear (533), the rear sear is pushed bock towards its forward position by the force of its spring so that the hammer (515) is locked into position. At the some time, the automatic sear (519) will, under the force of the left hammer spring (514), engage the notch in the front port of the hammer (57 5). • Ensure that the automatic sear (5 19) can be manually released from the hammer (515) without the hammer being decocked (part C of Fig . 9.5.o). • While holding the automatic sear (5 19) in the released position and being extremely careful not to trap your fingers, firmly pull the rear sear (533) rearwards and then check if the hammer (5 15) decocks correctl y (part D of Fig. 9.5 .o).

CHAPTER 10: INSPECTION AND ADJUSTMENTS Before any intervention on the P9Q® submachine gun, ensure to be familiar with the safety information given in chapter 4 of this Maintenance Manual. Before any inspection or ad justment, ensure t hat the submachine gun is perfectly clean.

1 0.1. CHECKING THE FIRING PRECISION (Fig. 1O.a) NOTE : In order to increase th e accuracy of the following checking procedure, it is recommended to secure the gun in a fixing such as a shooting ad justment device, a vice, ...

When fixing the gun into the , be careful not to tighten too hard so that the movement of the inside moving parts is not hindered and ensure that the fire selector (255) and the trigger (261) remain easily accessible. If no fixing is available, let the gun rest onto on stable surface (e.g. o sandbag), fire 1 shot more as recommended and eliminate the less accurate impact. The firing precision should periodically be checked by proceeding as follows : • Set the fire selector (255) at the position '1 ' {single-shot). • Aim the submachine gun at a well-determined point {P) on a safe target located at 50 m. •

Fire 10 single shots.

• At the target, check if the 10 impacts ore situated within a square with a side of 20 em.

If so, directly proceed to the next step. If not, repeat the shooting procedure at least twice.

If, during these next tries, the 10 impods ore still not situated within o square with o side of 20 em, this indicates that the barrel ( 131 ) of the submachine gun is showing signs of wear : replace the barrel and then restart this checking procedure. • At the target, determine the mean point of impact {MPI). • If the MPI corresponds to the imaginary point (P1 ), 10 em above the point of aim (P), the firing precision is correct.

Using on imaginary point (PI) for a range of 50 m is necessary in order to ensure o correct firing precision ot ranges up to 200 m. If not, the firing precision should be adjusted.

In case of the P90®, P90®LV or P9Q®LIR with standard optical sight (711 ), proceed as described in the following § 10.2. In the other cases, proceed as described for the optional sight presently installed on the gun .

10.5.

CHECKING AND GAUGING THE EXTRACTOR (435) Besides the periodic inspect ions, the extractor (435) should also be checked and gauged after each intervention (removal, disassembling, ...) on it. The checking and gouging procedure for the extractor (435) consists of checking its axial clearance.

The axial clearance of the extractor (435) is the distance between the tip of the claw of the extractor and the bottom of the housing for the cartridges in the front face of the breech block (C 1).

The distance represents the available space into which the rim of the cartridge case con fit. Proceed as follows : • Remove the moving ports group [ 3] as described in§ 7.1.

NOTE : Before carrying out the following checking a nd gouging procedure, ensure that th e housing for the cartridges in the front face of the breech block (C1) as well as the claw of the extractor (435) ore perfectly clean. •

Using the extractor axial clearance gouge G087, check th e axial clearance (435) by proceeding as follows (Fig. 1O.h) :

of the extractor

- Press the flat surface of the M INI end of the gauge G087 correctly against the bottom of the housing for the cartridges in the front face of the breech block (C 1). - Taking care to maintain full between the flat surface of the gauge and the bottom of the housing for the cartridges in the front face of the breech block (C 1), rotate the gauge G087 towards the claw of the extractor (435). - Repeat this operation for the MAXI end of the gauge G087. The axial clearance of the extractor (435) is correct if the lug on the MINI end of the gauge G087 con between the claw of the extractor (435) and the front face of t he breech block (C 1) and the MAXI end of the gauge cannot between the m.

In such o case, directly proceed to the following step. The axial clearance of the extractor (435) is incorrect if the lug on the MINI end of the gauge G087 cannot between t he claw of the extractor (435) and the front face of the breech block (C1) or the MAXI end of the gauge can between them.

In such a case, the extractor (435) and/ or its spring (431) should be replaced. For more in formation about the removal and the reinstallation of the extractor (435) and its spring (431), refer to§ 9.4. After having replaced the extractor (435) and/ or its spring (431), this checking and gouging procedure should be repeated. •

Before using the visible or infra-red laser, ensure to be fami liar with the safety information given in paragraph 4.4 of this Maintenance Manual.

NOTES : •

Before carrying out the fol lowing adjustment, ensure that the sight of the submachine gun has been adjusted correctly.

• When carrying out this adjustment, it is not required to fire the submachine gun : the gun should therefore be unloaded .

Checking the precision of the laser (Fig. 1O.j) • •

Ensure that the submachine gun is complete ly unloaded. Looking through its correctl y adjusted sight, aim the gun at a well-determ ined point (P) at

50 m. At the same moment, activate the visible or infra-red laser and then check if the laser dot (D) corresponds to the point of aim (P).

If so, the precision of the laser is correct. If not, the precision of the laser should be adjusted as described in the following § 10. 7.2.

Adjustment of the laser (Fig. 1O.i) •

Check the precision of the laser as described in§ 10.7.1. If the laser dot (D) corresponds to the point of aim (P), the following adjustment should not be carried out. If the laser dot (D) does not correspond to the point of aim (P), carry out the following adjustment.

• If a correction of the laser dot (D) is requi red, slightly turn one of the 3 hexagonal socket head screws (72 1) wh ich can be f ound at the f ront extremity of the frame (220). Fore more information, refer to the arrows on Fig. 1O.j. Do not turn a screw by more than

90° before checking the precision of the laser again.

Do not turn more than one screw before checking the precision of the laser again.

Excessive tightening of the screws (721) can cause irreversible damage to the incorporated loser unit : if the adjustment requires o clockwise rotation of a fully tightened screw, first turn the 3 screws by the same amount in the counterclockwise direction and then continue with the adjustment.

•

Check if the precision of the laser is now correct.

If so, the adjustment is terminated.

If not, repeat the adjustment until o correct precision is obtained for the laser.
