Saiga MK-107, 2015

In 2012, Kalashnikov decided to develop a variant of the AK-107 for the civilian market. Former civilian offshoots of the Kalashnikov weapon family were marketed under the Saiga brand , and so the project was initially named Saiga MK-107 . This Saiga MK-107 had the caliber 5.45 × 39 mm . In 2018, serial production of the final version of the SR-1 in .223 Remington caliber began and went on sale in May 2018.

The SR-1 is a gas pressure charger with a rotating head lock. Basically it is based on the Kalashnikov locking system with two locking lugs, but has two opposing gas pistons on top of each other. The barrel is free-swinging and is surrounded by the fore-end that is attached exclusively to the breech block.

Like the AK-107, the SR-1 is equipped with a counterweight that compensates for the recoil mass of the breechblock and thereby absorbs a large part of the recoil, so that the weapon is better placed on the target during the second shot. The system goes back to experimental weapons from the 1970s ( AO-38 , AL-4 and AL-7 ). The gas piston and bolt carrier on one side as well as the counterweight with the second gas piston on the other side are equipped with a toothing similar to a toothed rack and are connected to one another with two toothed wheels (AK-107/108: one toothed wheel). When the projectile leaves the barrel, the powder gases act on both gas pistons, that of the bolt carrier is pushed back and that of the counterweight is pushed forward. The gears synchronize the movement of both parts.

The weapon can be operated completely from both sides. For this purpose, it has a pin safety above the trigger guard as well as a clamping lever on the left and right side, which, as usual with Kalashnikovs, are firmly connected to the bolt carrier. Both gas pistons have their own return spring. The SR-1 has a magazine slot designed for AR-15 standard magazines and a slide catch. The magazine release button is located on the left side of the breech block.

An AR-15-typical, length-adjustable shoulder rest serves as the shoulder rest. The cap is designed to be stiffer than that of a Kalashnikov and carries the Picatinny rail . It is fixed to the end of the bolt housing with a bolt. This ensures that the sighting device is not adjusted when the weapon is partially dismantled.
