Withdrawn.....No longer for sale.
Colt 20" 1/7 twist government profile barrel was purchased as new take-off from a Blue lable gun. In new condition with barrel nut, A-2 Front sight base (No bayo lug), and handguard retainer.
Also have a NEW "F" marked Front sight base (with bayo lug) for use with Flattop uppers. I bought it to have fit to the above barrel but never did. It is new and must be custom fit to you barrel.
