Barrel 20'' .308 AR M118 1x11 Nitrided

Criterion .308 AR match-grade barrels are built around the M118 LR match chamber, engineered for compatibility with both 7.62×51 NATO and .308 Winchester rounds. This chamber design is tailored for optimal performance with longer, heavier projectiles. Thanks to its adaptable performance, this barrel is well-suited for everything from competition and tactical shooting to hunting.

The Hybrid contour design represents a well-balanced, medium-weight profile that strategically manages barrel mass to enhance heat management and maintain consistent barrel harmonics. It’s light enough for comfortable carry over long durations, yet durable and accurate enough to perform under sustained fire and demanding use.
