Technical characteristics of the hunting models

Design

Semi-automatic smoothbore gun with a gas engine.

• The adjustable piston is in the rifle tube and represents a design with a spring made of heat-resistant steel and shaped nuts. Depending on the tension of the spring, the powder gases stravlivaya slower or faster, thus providing stable operation of the mechanism of recharge for different batches of gunpowder and fractions.
• Barrel with chrome channel and the chamber. On the muzzle there is a thread for installing a replacement of the contractions. Nozzles are placed inside of the barrel and not extend it.
• The piston gas engine is connected to the slide frame hard massive rod. The shutter closes the bore oscillating wedge (patent George. Browning), will the cutout in the shank of the trunk.
• The recoil spring is wound on the tube store, so a possible upgrade of the stock and changing it to pistol grip.
• When shooting last bullet frame shutter stops in the rearward position. For the removal of the delay there is a button located on the right side of the receiver, above the hopper of the store. Among the elements of the control arms includes a lever forced feeding of a cartridge from the magazine to the bunker. It is located between the trigger guard and hopper. When the button is pushed back to the butt, a cartridge is fed to the Elevator. This locks the platoon trigger of a striker when moving the bolt back.
• The receiver is of aluminum alloy, window release liners is on the right.
• Trigger mechanism with two degrees of protection: button mechanical safety device that blocks the trigger, and disconnector drummer in the cylinder stopper, which prevents a shot when not fully latched the barrel.
• Button-check the fuse located in the posterior branches of the trigger guard. It moves perpendicular to the axis of the barrel. Left shift – position “Fire”.
• Polupoltina bed, made of solid wood or high impact plastic. The handle is flat, the butt stock with straight comb and has a slight slope to the axis of the barrel. The shock-absorbing recoil pad.

Picking and packing

The principle of operation

The weapon works on the principle of gas engine that uses the energy of a portion of the propellant gases from the bore. After the shot the piston is connected to the slide frame thrust is shifted back, resulting extracted the used cartridge case and the recoil spring is compressed. Platoon firing mechanism occurs at a bolt carrier rearward position. At the same time, the feed Elevator raises received from store in the bunker munition on the line loading. In the reverse movement of the cartridge is inserted into the chamber, the lever larvae shutter is raised and engages the notch in the shank of the trunk.

You can charge directly into the chamber and into the store. In the first case, first turn on the fuse, then slide is moved back and placed on hold. The cartridge is placed on the Elevator feed through the window of ejector sleeves. For chambering, click on the button located above the window of the bunker. The bolt carrier is going back quite vigorously, because it is impossible to substitute fingers under her pen.

To the store of ammo stacked through the lower window, which is necessary to lower the lever of the Elevator flow inside the receiver.

For the exception of a platoon of projectile and feed the cartridge in the chamber when unloading, use the lever located between the front branch of the trigger guard and hopper. He slides back, causing the ammunition slipping out of the shop with the shutter closed. When removing the bolt back the cartridge rises to the level of the window, release liners, and she is fixed at the delay. After removing the cartridge, press the release button with a delay, and then retry the operation several times.
