As promised, more pictures
Even with an 8.3" bbl. these weapons have pretty light recoil. They shoot the successor cartridge to the Russian 7.62x39mm round, the 5.45x39mm round. It was developed as a response to the M-16's 5.56x45mm cartridge. Ballistically speaking, this cartridge is maybe 10% less efficient on paper. However, the original military ball ammo (called 7N6 in Russia) has a unique bullet that creates a huge temporary cavity and tumbles in tissue more than the M-16's cartridge.Nasty lookin' little bugger. I'd bet its a real kick in the pants to fire.
