These are brand new production AKM47 7.62x39 cold hammer forged bolt carriers produced by WBP in Rogow, Poland. These new unserialized mil-spec carriers are featured in all of the WBP firearms we import and they come ready to be polished for smoother action. These feature a ZINC coating for lubricity and rust resistance!

Gas piston is threaded and riveted into place, with the rivet ground down flush with the body. Some pistons will have wobble, this is completely normal and will not impede function.

These work with just about all standard 7.62x39 AKM spec firearms.
