I have a custom built Bulgarian 74' (Cal. 5.45x.39) built on a 1.6 Arsenal USA receiver in excellent condition, only 20 rounds fired (excellent bore) that I'm willing to trade for a AR-15 (M-4) Govt. profile COMPLETE upper. Upper must include all parts, B/C,C/H, hand guards, barrel etc.
I would prefer the 14.5" barrel with a perm. 1.5"/2" flashider, or a light weight 16" pencil barrel. I'll send pics if interested.
