Criterion DCM Stainless 20" 223 Remington Heavy Service Rifle Barrel 1:7.5 Twist

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. Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith.
