The semi-auto hunting assault rifle (Huh?)"OP-SKS" is designed for middle (medium?) and big games (what games?) in commercial purposes (sporting purposes?) in different weather and climatic conditions (redundancy, anyone?) at the environment temperature from -50° up to +50° (Ooookay...). The assault rifle is created based on the famous SKS-45 Simonov semi-auto rife and is output (Chambered?) for a cartridge of the caliber 7,62х39.
The automatic reloading of the rifle is carried out due to use of the energy of powder gases moved from the bore into the gas chamber and the energy of the return spring.
The bore is locked by warp of the bolt (what???), when the bolt carrier slides length wisely (as opposed to length foolishly?). The hammer-type firing mechanism provides shooting by single shots and saving the gun (from what, exactly?).
The flag-type safety device is situated inside the trigger guard of the firing mechanism body.
The feeding of the rifle is carried out from the fixed magazine. Inside the stock from the side of butt there is a case with the accessories destined for cleaning and stripping the gun.
