Price is firm. PSA lower and upper is PTAC 16" Carbine Length 5.56 NATO 1:7 M4 Nitride. I will include (2) Pmags. Live in North Charlotte, but work in South Charlotte. All laws followed. No trades, priced to sell quickly. *note* the discoloration is just lint or something from being in my safe.. I have fired 2 mags through this.
