What We’ve Seen
We’ve run these barrels extensively in-house and continue to be impressed. Borescoping reveals clean rifling and consistent bore quality. Headspacing has been spot-on with both CMC BCGs and Superlative Arms BCGs—ensuring reliable function with minimal fuss.
When paired with the included gas tubes and a quality carrier, these barrels create a tightly tuned gas system that runs clean and consistent.
Need more than just the barrel? We stock complete bolt carrier groups, adjustable gas blocks, and 22 ARC factory ammo—everything you need to complete a high-performance build.
