BRT 18" MATCH STAINLESS Barrel 6ARC

Black River Tactical MATCH STAINLESS barrels start with a match grade blank using a precision button rifling process and certified material. The blanks are lead lapped by hand to produce an exceptionally smooth bore finish. The 416R material is naturally resistant to corrosion.

*NOTE: These are overruns produced and marked for BCB.

Features

• Button Rifled and Stress Relieved for consistent accuracy using a hand lapped true match grade blank.
• 416R Stainless Steel for excellent service and resistance to corrosion. This steel was developed specifically to address the unique requirements of precision firearm barrels and includes stringent requirements for composition and purity.
• 6mm ARC Chamber for compatibility with all commercially available 6mm ARC ammunition. Our multi-step process produces true mil-spec chamber dimensions with excellent concentricity and includes separate operations for throating and chamber polishing.
• Gas System tuned for reliable use with and without a suppressor attached. Our gas system configurations and gas port dimensions are the product of extensive engineering backed by exhaustive testing. The results are an balance of wide reliability margin, smooth operation and seamless suppressor compatibility with near zero "gas to face" issues.
