New Bulgarian AKS-74s Krink kit in 762x39 still in the original packaging from KVAR. This is one of the parts kits KVAR brought into the US for a short while back in the early 2000's. This is not a kit from a demilled gun; parts are all new, unused, and have never been assembled into a complete weapon. The only thing this kit lacks is the trunion and the receiver.
MG42 barrels in 308. These are surplus, but still have good rifling and lots of life left in them.
AMD-65 parts kit. Includes the original (imported) barrel in the trunion.
Would also consider trades involving:
G17.3 complete slide, milled for RMR
AR parts - LPK, BCG, etc.
S&W 686 or 625
LMT MWS or parts
