AK47 Pistol gas Piston 5& 1/8" end to end length.
Unknown what model this fits, but most likely a pistol of some type.
This may fit a Draco, but not sure.
I have some surplus draco bolt carrier groups. Some have the same length gas piston, some a little bit longer.
Sold as is. I dont know where these pistons came from, and neither did my supplier.
