I'm selling a new, unfired Colt 14.5" M4 barrel. It is chrome lined, 1/7 twist, with M4 feedramps and the F marked front sight base. The barrel is marked CMP 5.56 NATO 1/7. This is the stripped barrel only, no front sight, flash hider, or delta ring. I accept postal money orders or Paypal (+3%). The price includes shipping to the continental US.
