Criterion Barrel (20" .223 Match AR15 Service)
Designed with service rifle and high power competition in mind, Criterion-manufactured Heavy Service Rifle and NRA Match contour barrels offer extreme accuracy potential for competition shooters. Uniformity of the bore, groove, twist, and a hand lapped finish improve the accuracy potential of each match quality barrel. The 1-7.7 twist on the 20" Heavy Service Rifle model allows for improved performance with heavier 80 gr. Sierra MatchKings without sacrificing the performance of lighter ammunition. These barrels are offered in both pre-ban (1/2?28 threaded muzzle) and post-ban (11 degree target crown) configurations.
Flats are milled into the barrel for windage adjustable front sight bases (will work with any front sight base, even without adjustments)
Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith.
