Barrel 20'' .308 AR M118 1x11 Chrome Lined By Criterion

Criterion’s .308 AR match-grade barrels are built with the M118 LR match chamber, offering compatibility with both 7.62×51 NATO and .308 Winchester cartridges. This chamber design is fine-tuned for enhanced performance with longer, heavier bullets. Its adaptability makes it an excellent fit for a wide range of shooting needs—from tactical and competitive use to hunting scenarios.

The Hybrid contour, Criterion’s most widely used barrel profile, provides a well-balanced mid-weight design. It features intelligently distributed material to help manage heat and maintain consistent barrel harmonics. Lightweight enough for extended carry in the field, it also holds up to hard use and delivers excellent accuracy even under sustained firing conditions.
