Colt 14.5" m4 barrel. Barrel is used, finish is worn. Not sure of round count, but rifling and chamber looks very clean. Date stamped 08/09.
Comes with a Stripped A2 Front Sight post that I milled to it but no small parts (Swivel, sight post, detent, spring, or taper pins (oversize). It looked dead straight centered when I sighted it with against a laser in the bore. You can use it or pull it and put on a lo pro gas block.
I am getting rid of this because I have too much stuff and I already have some other 14.5" barrels...
Will take $135 shipped, or may trade for a nice free float 15" handguard, a good bcg, or a giesle GS2 Trigger.
