I just got a Colt M4 barrel from ChrisM in trade for other Colt parts. It has bayonet lug, delta ring, flash suppressor and crush washer. Less than 300 rounds in excellent condition. I would like a similar Colt 16" LW barrel (i.e. with flash suppressor; bayonet lug is of no importance). E-mail for pic.
Edited to add: This is a 1/7 twist barrel. I want a 1/7 twist, "pre-ban" barrel.
