Hunting rifles ST-153 and ST-155

Semi-automatic gun model ST 155
Semi-automatic gun model ST 155 cal. 12/76 has an inertial recharge system, which guarantees easy operation and reliable operation.
The inertial system is simple and reliable.
Its operation is provided by only 3 elements – the shutter frame, inertial spring and the shutter itself.

No powder gases, gas pistons and sludge! Locking the barrel is carried out by means of combat stops on the larva of the shutter, which during the shot fix the larva. After a shot with the force of recoil, the rifle throws back by inertia, along with it throws and the bolt locked tightly behind the trunk. And while the shutter frame, due to its inertia, strives to stay in place, the bolt moves backward relative to the shutter frame with compression of the inertial spring. The larva rotates and the trunk is unlocked. Further, the residual pressure of the powder gases in the barrel casts the bolt together with the slide frame backward, compressing the return spring. In this case, the shot cartridge case is ejected, and on the return stroke of the bolt group – feeding of the new cartridge into the chamber. Expanding, the spring pushes the bolt forward and locks the barrel.

The inertial recharge system is much purer than the gas outlet. It is only necessary to clean the barrel bore and, if necessary, the bolt group. This at times saves you time.
Semi-automatic gun model ST 155 cal. 12/76 has a barrel length of 710 and 760 mm. The store capacity is 3 + 1 (12/76) and 4 + 1 (12/70).
The barrel is made of light alloy, which provides sufficient strength and ease of construction.

The applique is made of Turkish walnut, and also has a rubber backplate for softening the recoil.
The quality of assembly and processing of the details of the gun makes it one of the best in the “price-quality” ratio.

Semi-automatic gun model ST 153
Semi-automatic gun model ST 153 with gas removal system recharge is a modern technological weapon that can satisfy the demands of even the most demanding user.
A proven gas-evacuation system, the principle of which is the removal of the powder gases from the barrel bore into the gas-chimney with the subsequent actuation of the piston, thanks to the engineers of our company allows the shooter to use a wide range of ammunition, from 28 grams. up to 52 gr.
Shotgun model ST 153 cal. 12/76 has a barrel length of 710 and 760 mm. The barrel is made of light alloy, which provides sufficient strength and ease of construction. The fore and butt are made of practical and durable plastic. The capacity of the store is 4 + 1, the weight of the gun is not more than 3.2 kilograms.
The quality of assembly and processing of the details of the gun makes it one of the best in the “price-quality” ratio.
