Colt 11.5" Barrel Assembly and Complete Bolt Carrier Group
These barrels come direct from Colt. They have had one magazine put through them and spent the rest of the time in armorers' courses. The kit includes everything depicted in the photograph, including the barrel, front sight post, flash hider, and complete bolt carrier group. The barrels are marked, "C MP CB".
Please note, these kits come as-is from the armorers' courses. Any wear will vary from unit to unit.
