Black River Tactical SUBGUN Barrels are designed and built to meet the needs of professional shooters who require a balance of accuracy, durability and value.
Black River Tactical SUBGUN barrels start with a high grade stress relieved blank using a precision button rifling process and certified material. The barrels use a medium-light profile to keep weight down while maintaining strength. This produces a balanced weapon when other accessories are added. The barrels are finished with a QPQ Nitride process that maintains peak accuracy and withstands challenging environments.
Black River Tactical SUBGUN 9mm AR barrels deliver the performance to get the job done in demanding real world conditions.
Features
Large Radius Feed Ramp for reliable feeding of hollow point and defensive ammunition. A wide variety of loads from Federal HST to 147gr flat nose loads, are easily fed and chambered from Glock and Colt magazine lowers.
9x19mm Chamber for compatibility with a variety of military and civilian 9mm ammunition. Our multi-step process produces true chamber dimensions with excellent concentricity and includes separate operations for throating and chamber polishing.
Button Rifled and Stress Relieved for consistent accuracy. Our precision button rifling process produces an exceptionally straight and smooth bore finish with ideal land and grooves profiles, all of which are key to maintaining accuracy.
QPQ Nitride Chamber and Bore for excellent service life and resistance to corrosion. More than a surface finish, this treatment converts the outer surfaces of the steel into a hard composition with similar properties to hard chrome plating, but without any dimensional changes. This new surface improves extraction and velocity while resisting fouling and corrosion.
