Description of the F N Rifle

(Mauser System)

The rifle Is composed oi the following main parts:

1. The barrel with front-and rear sight.

2. The locklng-and firing mechanism.

3. The repeating mechanism.

4. The stock with hand guard.

5. The fittings.

6. The bayonet.

1. — THE BARREL has a length of 589 m/m. (or 740 m/m.) and its reinforced rear end is screwed into the body. The rifling is righthanded and consists of four helical grooves.

The sighting apparatus consists of rear sight and front sight.

The rear sight is of the tangent cam pattern and is composed of:

the bed and cam with spring, the graduated tangent, and the slide with spring pawls.

The bed Is tinsoldered to the barrel and has in its fore part a threaded recess in which the fixing screw of the hand guard is located. This screw engages in the barrel and rigidly connects the bed with the barrel. The sides of the bed form the cam and the hinge for the graduated tangent.

A spring located in the bed of the rear sight tends to Keep the tangent on the bed. The tangent has on its upper and lower surface graduations corresponding to 200 to 2000 metres in steps of 100 metres in very legible figures, which allow easy changes of the sight in any position of the rifleman. In the upper end of the tangent is the triangular sighting notch. The 2 aides of the tangent are provided with notches in which the spring pawls are retained. By pressing these pawls, the slide can be moved in order to obtain the elevation of the required range. By releasing the pressure on the milled ends of the pawls, the latter engage under the effect of the pawl springs in the corresponding notches of the tangent. The tangent is secured to the bed by means of 2 small lateral bearings which rest on the hinge. A pin running through the leaf and fastened to the hinge prevents losing the tangent in case the spring should break.

On the front end of the barrel is soldered the fore sight ring and block which form the support of the fore sight. The fore sight block and the ring are pierced by a screw which engages in the barrel and ensures an absolute rigidity of the whole.

The milled rear portion of the fore sight block renders the foresight prominent whilst the effect of reflection is minimized. The triangular foresight is dovetailed into the block and can be adjusted sideways.

2 — THE LOCKING- AND FIRING MECHANISM is composed of the body, the bolt and the trigger mechanism.

THE BODY (in which the barrel is screwed) receives the bolt.

The body head is formed with 2 lugs provided with ramps in front of which the locking lugs are placed when the rifle is locked. A ramp ensures the regular introduction of the cartridges in the chamber.

The lower part of the body head carries the lug which engages on the cross piece secured to the stock. This cross piece transmits the recoil to the stock ; the lug itself has a tapped recess into which is screwed the front screw of the trigger guard.

The body is cut away in its middle part in order to allow of the introduction of the cartridges in the magazine and the ejection of the fired cartridges. The left side is further cut away to facilitate the pressure of the thumb on the cartridges at the moment of loading them into the magazine. The left side of this part of the body is provided with a longitudinal groove which serves as a guide for the corresponding locking lug of the bolt. The bottom of the middle part of the body is removed to allow loading of the cartridges.

Besides the grooves of the bolt lugs, the bridge part of the body has an internal longitudinal groove which serve as a guide for the rib arranged on the cylindrical body of the bolt. This rib ensures the guiding of the bolt when its left lug faces the opening made in the side of the body to allow of the passage of the thumb when loading the rifle. On the left side of the bridge is the opening for the bolt stop and the ejector whilst a groove provided with a ramp is arranged in the bottom of this part of the body to receive the safety lug of the bolt.

The bolt stop and the ejector are both fastened at the left side of the bridge of the body by means of the same pivot screw. The bolt stop has a catch projecting into the interior oi the body. The left lug of the bolt comes into contact with the catch when the bolt is entirely drawn back. The bolt stop also serves as a support for the ejector which, passing through the groove made in the left lug, protrudes into the bolt head the instant that the bolt is completely drawn back, thus causing the cartridge case retained in the bolt head by the extractor claw, to swing to the right.

The bolt stop and the ejector are actuated by a double spring fitted to the first named part.

The front portion of the bridge of the body has a recess for the insertion of the loading clip.

The rear part is cut out in the shape of a cam against which the flat side of the bolt lever presses when opening the rifle, in order to disengage the fired shells. It has further a bearing which serves as a stop for the bolt lever at the moment of the opening of the rifle.

The tail of the body is provided with a longitudinal groove in which moves the stud of the cocking piece. The bottom of this groove has 2 holes, one for the sear nose, the other, which is tapped, is for the rear screw of the trigger guard.

THE BREECH is composed of the following parts:

The bolt.

The extractor ring.

The extractor.

The firing pin and its spring.

The cocking piece.

The bolt plug.

The safety.

The spring catch of the bolt plug.

THE BOLT. — The upper end of the cylindrical body of the bolt is cupshaped. The center of this upper end is pierced to let the point of the firing pin pass. The head or the bolt has 2

locking lugs provided with chamfered edges which facilitate the locking of the rifle; the left lug is split in order to allow of the passage of the ejector. A semi-circular groove let into the bolt head and provided with a small ramp serves as a guide for the extractor. The cylindrical body of the bolt carries the extractor locking ring with its 2 small lugs and it has 2 oblong holes arranged longitudinally which serve as escapes for the gases. Should a cartridge case break or a cap be pierced, these apertures serve as escapes for the gas towards the sides and back without danger to the rifleman.

The body of the bolt also shows in the axis of the bolt lever a longitudinal rib, which engaging in its groove on the upper portion of the bridge of the breech, guides the bolt when it is drawn rearwards.

An additional lug on the rear part of the bolt serves to increase the safety of the rifleman. At the moment of locking, this lug engages in the groove provided in the bottom of the bridge. It serves as a special locking device and additional safety in case the front lug should give way under the pressure developed by the cartridges. The device therefore protects the rifleman against any accident and increases his confidence in his rifle.

The bolt is provided with a lever terminated by a knob. The strengthened rear part of the bolt shows the cocking notch provided with a cam which forces the stud to recoil and to clear the sear nose at the moment of the closing movement. This part of the bolt is also provided with the locking recess for the safety spindle.

The inside of the bolt is bored out to receive the firing pin, its safety recesses and the main spring and is threaded at the end for connection with the bolt plug.

THE EXTRACTOR RING is provided with small lugs connecting the extractor with the bolt on which it can freely rotate.

THE EXTRACTOR is fastened to the bolt means of the extractor ring so that it can be rotated. II has a claw at the end of the bolt which engages in the groove of the cartridge. The head of the extractor carries the extractor guide sliding in the semi-circular groove provided in the bolt head. At its rear end the extractor is terminated by a lug resting upon the bolt. The great length of the extractor gives it such a flexibility that it can grasp a cartridge put by hand into the chamber. Its slightly curved form allows of its ac ing as a spring ensuring in this way its proper fastening upon the bolt.

THE FIRING PIN AND ITS SPRING. — The firing pin consists of the head drawn out to form the firing needle, the flange with its two chamfered safety surfaces which serve as a support for the striker spring, the cylindrical body flattened on two opposite sides for the passage of the cocking piece and the rear end with its three interrupted grooves corresponding with three bearings arranged inside the cocking piece. An incorrect connection of the firing pin and the cocking piece is impossible, as one the grooves and the corresponding bearing are broader than the 2 others.

The spring of the firing pin rests with its front part against the flange of the pin and at the other end against the front portion of the bolt plug.

THE COCKING PIECE is provided with a stud the front part of which is caught by the sear at the moment of cocking, thus retaining the cocking piece and consequently the firing pin, the cocking piece being rigidly connected with the latter part by its three interior grooves. The cocking piece has a second stud placed in the reverse direction of the first which has the purpose of preventing the introduction of foreign substances in the mechanism.

The stud is prolonged by a nose with a ramp. As the ramp of this nose is in contact with the cam of the cocking notch, the disengagement of the stud from this notch is facilitated when turning the bolt to the left in order to open the rifle. The cocking piece has further at its right a groove which allows of cocking the firing pin with the aid of a cartridge case; in case of missfire, it is therefore possible to recock the firing pin without being obliged to open the rifle.

THE BOLT PLUG is connected with the bolt by means of a saw thread. It maintains the firing pin and the cocking piece always in a correct position to each other. The strenghtened front part of the bolt plug protects the rifleman against blow backs.

In the upper part of the bolt plug is fitted the safety spindle and in the left the spring caich.

THE SAFETY DEVICE consists of the safety leaf and the safety spindle which are rigidly connected. This spindle is notched in such a way that the smooth portion, according to the position in which it is put, occupies or not the safety notch of the bolt, locking thus the bolt plug or disengaging it from the latter.

When the safety wing is pressed down to the right, the head of the safety is placed in front of the cocking piece forcing the latter back; as the sear is no more in contact with the cocking piece, it has no longer effect on the cocking piece and the depression of the sear cannot produce the discharge of the rifle. The safety head is provided with bevelled edges which facilitate the action of the safety on the cocking piece.

THE SPRING CATCH OF THE BOLT PLUG slides into the safety notch when the bolt is pulled rearward, thus connecting the bolt plug rigidly tot the bolt. When the bolt is pushed forward, the safety catch comes into contact with he rear part of the body, thus forcing the catch to return to its recess in the bolt plug and, consequently, to disengage from the safety notch; the bolt is thus set free and can turn to lock the rifle.

THE TRIGGER MECHANISM consists of the trigger bar with sear, the trigger and the spring. The trigger mechanism is fastened beneath the body by means of the trigger bar pin.

The trigger bar comprises the recess tor the trigger spring and its rear portion forms the sear nose.

The trigger spring rests one end against the bottom of the body and the other end on the trigger bar.

The trigger is secured to the trigger bar bv means of a riveted pin.

The upper part of the trigger forms 2 cams ; under the effect of the trigger spring, the front cam is always in contact with the bottom of the body, the other one only touches it when the trigger is pulled.

3. — THE REPEATING MECHANISM is composed of the magazine, the cover plate of same, the magazine spring and the magazine platform. The front end of the cover plate of the magazine rests in a groove arranged in the magazine and serves as a recess for the magazine spring, whilst its rear part is held by a spring bolt located in the rear stud.

The magazine spring connects the cover plate of the magazine with the platform to which it is secured by 2 bearings.

The platform is shaped to ensure the correct feeding of the cartridge at the moment of entering into the chamber and facilitates this movement.

The magazine can hold 5 cartridges placed in zigzag fashion.

The sides of the magazine are formed by the trigger guard which further consists of the finger guard, the recesses of the-locking screws of the finger guard and their check screws.

4. — THE STOCK WITH HANDGUARD. — The stock is of walnut made in one piece and provided with a pistol hand grip.

The stock has at its foremost part the bayonet attachment and is provided with the spring seat of the upper band, the seat of the lower band, of the cleaning rod stop and of the cross piece.

At the lower part of the stock is secured the base of the bottom swivel and its swivel.

The rearmost portion of the stock is covered with a butt plate secured by means of 2 screws.

A boring let into the inside of the stock serves as a recess for the cleaning rod.

The different borings made in the stock serve respectively as a seating for the barrel, the lower part of the breech, the trigger guard which forms the magazine, the firing mechanism and the rear screw of the trigger guard. (This seat is fitted with a metallic casing).

The upper part of the banel is covered by a hand guard hoi*

lowed out at its lower part to give access to the base of the rear sight.

The hand guard is provided with a spring secured by means of 2 screws; this spring, together with the screw of the rear sight base fixes the hand guard to the barrel.

The hand guard is secured to the stock by means of the lower band.

The hand guard does not only protect the rifleman against the heating of the barrel, but also improves the precision of the rifle by securing the barrel firmly to the stock.

5. — THE FITTINGS consist of the cleaning rod. It screws into a nut let into the stock. The other end is provided with a slot for the rag and is tapped so as to allow of 2 rods being screwed together for the cleaning of the barrel;

the upper band and its spring;

the bayonet attachment;

the lower band and its spring;

the swivel of the lower band;

the front-and rear screws of the trigger guard and the check screws;

the cross piece in the breech (secured by means of a nut);

the bottom swivel; the muzzle cover; the sling.

6. — THE BAYONET consists of the grip, the guard with ring which surrounds the end of the barrel when the bayonet is fitted to the rifle, the blade and the steel scabbard.

The bayonet is secured to the rifle by means of the bayonet attachment. This is provided with a notch in which the spring pawl, lodged in the grip of the bayonet, engages, thus connecting the bayonet rigidly to the rifle.
