Automatic special AS “VAL”

Special Machine (AS) “Val” established at the Central Research Institute of Precision Engineering (TsNIITOCHMASH) by designers P. Serdyukov and V. Krasnikov. Adopted in 1987 in the military special forces and the Interior Ministry. It is intended for defeating manpower under conditions requiring silent and flameless firing at a range of up to 400 meters. The machine gun was created on the basis of a special sniper 9mm rifle. BCC “Vintorez”.

The machine is based on the principle of gas-automation with a long stroke of the gas piston. The gas piston is located above the barrel and is rigidly connected to the bolt carrier. The barrel is locked with a butterfly valve having 6 lugs, for cuts in the receiver. The receiver is made by milling method of steel. The trigger mechanism allows maintaining single and automatic fire.

The safety lever is made by type Kalashnikov assault rifle and in the on position overlaps the groove for the arm loading the weapon. A separate translator of fire modes is located inside the trigger guard, behind the trigger, and provides fire modes with single shots and bursts.

The silencer is easily separated from the weapon and disassembled for cleaning, but firing from a weapon with the silencer removed is not allowed.

The silencer integrated with the barrel provides sound suppression, is about 130 dB and a flash of flame. There are no replaceable parts in the silencers, which guarantees its survivability. Au easily disassembled into large assemblies: barrel with receiver, automation parts, firing mechanism, forearm, silencer, sighting device, magazine and butt. All nodes can be placed in a special diplomat, size 450x370x140mm. Assembly is carried out in 30-60 seconds.

A carry case may also be used for transfer. Sights include a fly and a sector sight, marked from 25 to 400 meters, mounted on the muffler housing. In addition, on the left wall of the receiver is a strap for mounting brackets for optical or night sights.

Through the use of powerful ammunition SP-5, SP-6, PUB-9, at a distance of 100 meters a bullet pierces a bulletproof vest of the 3rd class, with 200 meters 6 mm steel sheet, and with 500 meters 2 mm steel sheet.

The bullet of the SP-6 armor-piercing cartridge is capable of disabling a car and even lightly armored military equipment. Pistol grip and machine gun shank made of plastic, butt made of steel tubes, folding left side. Established stores have a capacity of 20 rounds and are made of black plastic; 10-round rifle magazine is also allowed BCC “Vintorez”.
