SA vz-58, 7.62x39mm, only thing in common with the AK is caliber, nothing else. Love to shoot it, light recoil, accurrate and fun. This one also sports the extended bolt release from Niet Arms, and after hits picture installed the extended amibextrous mag release from the same great guys. Also has US made gas piston and metal trigger, so all surplus mags are uasable, 922 compliant. With rare 20 round mag, Zahal stock folding extended. I always gotta be different!
