Barrel 20'' .308 AR M118 1x10 Chrome Lined By Criterion

Criterion’s .308 AR match-grade barrels are designed with the M118 LR match chamber, making them suitable for both 7.62×51 NATO and .308 Winchester ammunition. This chamber is tailored for enhanced performance with longer, heavier projectiles. Its adaptable nature makes it an excellent choice for a wide range of applications, including competitive shooting, tactical operations, and hunting.

The Hybrid contour strikes an ideal middle ground in barrel design, combining moderate weight with strategically distributed material to promote superior heat dissipation and stable barrel harmonics. It’s light enough for extended carry in the field while also delivering reliable, high-level performance under demanding conditions and sustained fire.
