I have a rifle length standard weight FF 4 rail handguard in VG condition. I'd like to trade for a chrome lined govt profile barrel in 16 or 20" length. The barrel doesnt have to be perfect but does have to be shootable and not a pitted POS. Includes barrel nut, lock ring and 3 black magpul rail covers. No front cap included ( not a necessary part ) Can toss in some other small AR parts if you need them.
