Barrel was new in the tube when I bought it and installed on the same Armscorp Receiver by Warbird years ago. I put maybe 60 rounds through it over the years. I decided that I wanted a GI barrel and forged receiver so these are for sale. The barrel is a General Dynamics NM. They were removed by Ted Brown while swapping out the barrel and receiver. Barrel is $350, Receiver $400. Shipping is extra.
