Abstract

FIELD: weapons and ammunition.

SUBSTANCE: proposed rifle comprises breech frame, breech chamber with bolt, trigger and firing mechanism and magazine. Breech frame crosswise slot accommodates the base of reload handle with its central part furnished with limit ledges arranged between breech frame side surface and breech box inner wall inner surface. "П"-like switch is fitted on axle arranged in the handle base front part extending from breech box and handle safety lever is arranged behind it. Spring is fitted between handle base and safety lever. Handle base has a hole, elongated crosswise, to receive axle fitted in aforesaid switch. Said axle, with switch turning, acts on curvilinear surface of handle safety lever part, below its axis of rotation, moves short arm of L-like ledge out from breech box ledge. Now, breech frame and reload handle can move rearward.

EFFECT: improved performances due to simplified reloading.

Description

The invention relates to the field of weapons technology and can be used in sniper and sporting and hunting weapons.

Known magazine rifle sample 1891/1930. [1], which includes a barrel with a receiver, a bolt, a magazine, a trigger mounted on the receiver to which the box is attached. After a shot, when unlocking the bore, the shutter stem handle rotates to the left, after which the shutter retracts behind the shutter stem handle. When reloading a rifle, the bolt moves forward by the handle of the shutter stem and rotates to the right.

The disadvantage of this design is the violation of the aiming of the weapon at the target when reloading.

Known sniper magazine rifle containing a barrel with a receiver, bolt, bolt carrier, trigger mechanism, store. A reloading handle with a fuse in the form of a two-shouldered lever with a L-shaped protrusion and a two-shoulder lever for pre-stragging the shutter is installed in the transverse groove of the shutter frame [2].

When reloading this rifle, it is necessary to first turn off the fuse of the handle with the thumb of the hand, removing its L-shaped protrusion from the interaction with the receiver, and only after that, by turning the other fingers on the shutter pre-release lever, the shutter frame can be moved back with the shutter.

The need for strict adherence to the sequence of actions when reloading a rifle complicates the reloading process, which is an operational disadvantage of the above rifle design.

The aim of the invention is to improve the operational characteristics of weapons.

This goal is achieved by the fact that in a sniper magazine rifle containing a barrel with a receiver, a bolt, a bolt carrier, in the grooves of which there is a reload handle with a fuse in the form of a two-shouldered lever with a L-shaped protrusion, trigger mechanism:

- in the middle part of the base of the handle there are made restrictive protrusions located between the side surface of the bolt frame and the inner surface of the side wall of the receiver;

- the handle fuse is mounted on an axis in a blind rectangular cavity made in the base of the handle;

- in the middle part of the fuse of the handle and the base of the handle are made nests in which a spring is installed;

- the handle fuse switch is made in a U-shape, covering the base of the handle, and mounted on its axis protruding from the receiver;

- between the axis of the fuse of the handle and the limiting protrusions in the base of the handle, a hole is made, elongated in the transverse direction, in which the axis is mounted, fixed in the switch, with the possibility of contact with a curved surface made on the facing part of the safety handle;

- the switch is mounted on the axis with the possibility of rotation in the direction of the side surface of the base of the handle until it stops.

The foregoing is illustrated by drawings, where:

- figure 1 shows a top view with a partial cut along the reload handle;

- figure 2 shows a General view of a sniper magazine rifle (right view).

A sniper magazine rifle contains a barrel with a receiver 1, a bolt with a bolt frame 2, a trigger mechanism with a trigger 3 and a trigger 4. In the transverse groove in the bolt frame there is a reload handle consisting of a base of the handle 5, a fuse 6 in the form of a two-armed lever with a L-shaped protrusion 7 and a switch 8. In the middle part of the base of the handle there are restrictive protrusions 9 located between the bolt frame 2 and the inner surface of the side wall of the receiver 1. The handle fuse is installed flax on the axis 10 in hollow rectangular cavity 11 in the base of the handle. A spring 12 is located in the sockets of the base of the handle and the fuse. In the forward position of the reloading handle, its L-shaped protrusion 7 of the fuse rests on a bevel 13 made in the wall of the receiver. The switch 8 fuse handle in the form of a U-shaped form covers the base of the handle. It is mounted on an axis 14 at the end of the protruding portion of the base of the handle. At the base of the handle there is a laterally elongated hole 15 in which an axis 16 is mounted, fixed in a switch. The axis 16 is in its extreme forward position due to the impact of a spring-loaded fuse on the handle. The longitudinal groove 17, along which the handle moves when reloading, ends with a window 18, through which the limiting protrusions 9 pass when the handle is installed in the transverse groove of the bolt frame 2. When assembling the rifle, the transverse groove in the bolt frame 2 is aligned with the window 18, after which the reload handle is installed . Pushing the handle together with the bolt frame forward, fix the recoil pad. Restrictive protrusions 9, located between the side surface of the bolt frame and the inner surface of the side wall of the receiver, fix the position of the handle in the bolt frame without additional fastening. When the bolt frame moves forward, the bolt from the magazine 19 sends another cartridge to the chamber. At the end of the stroke of the bolt frame, the barrel bore is locked by a bolt, while the L-shaped protrusion 7 of the handle guard falls over the bevel in the receiver, fixing the position of the moving parts in the forward position. After a shot when reloading, the fingers of the hand, acting on the switch 8, turn it. The axis 16, mounted in the switch, moving in the transverse hole 15, expands the fuse 6, the L-shaped protrusion 7 of which is out of engagement with the bevel 13 of the receiver. The bolt frame with the shutter for the reload handle moves back all the way to the back plate, while in the rearward position the handle is in front of the window 18 in the receiver.

The proposed technical solution is implemented in a prototype sniper rifle and tested with positive results. It allowed to simplify the recharging process in comparison with the prototype, which improved its operational characteristics.
