The Soviet Arms AKS-74U "Krinkov" pistol features a side folding rear trunnion, hinged dustcover, and short barrel for the most compact AK PSA has offered to date. This pistol is equipped with a black triangle side folding pistol brace, hinged dustcover with integrated rear sight, ALG trigger, Soviet Arms grip, and the new JMAC Krink rail. The original AKS-74U was adopted in 1979 to bridge the gap between a sub gun and a full-length rifle. This Soviet Arms AKS-74U is chambered in .300 Blackout and still maintains all the charm and aesthetic of the original 5.45x39mm Krinkov, but in an easier to obtain caliber. **JMAC Krink Rail Requires A Different Gas Block and Needs Gunsmithing To Change JMAC Krink Rail Pistols must be shipped to a valid, current Federal Firearms Licensee (FFL).
