TRADE PENDING TO JDIXON22 i have a centerfire B kit i would like to trade for an ar-15 barrel. i have done nothing to the kit except grind the rivets flush on the rear trunnion. there is a very small amt of rust on the barrel. this kit did come with matching numbers on the bolt and front trunnion. i bought this kit early with the intention of a build but never did. it came with a makarov holster as well. it is still in the box like it came. looking for a pre ban barrel 16 or 20" with a threaded end for a fh.pecil barrels from retros welcome also. not looking for postban barrels at all.
