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.

Disclosure: Chrome-lined barrels are finished chambered and cannot be altered. They may not be compatible with all rifle receivers and/or bolt combinations. While most rifles are designed to accommodate chrome-lined barrels, some receivers/bolts may have tolerance allowances that can prevent the barrel from being properly headspaced. It's important to carefully consider the compatibility of a chrome-lined barrel with your rifle receiver before making a purchase. If you're unsure whether a particular barrel or bolt will fit your rifle, contact us for information about our headspace verification services. It is the only way we can guarantee your completed rifle is within specs and safe to fire.
