Bravo Company Manufacturing 16" 5.56 NATO 1:7 Mid-Length Government Profile AR-15 Barrel

Bravo Company Manufacturing 16" 5.56 NATO 1:7 Mid-Length Government Profile AR-15 Barrel

The Bravo Company Manufacturing 16" AR-15 barrel is built around a 5.56 NATO chamber, 1:7 twist rate, and mid-length gas system for a dependable general-purpose rifle configuration. Constructed from 41V50 chrome moly vanadium steel with a chrome-lined bore and chamber, manganese phosphate finish, and .750" gas journal, this BCM barrel provides a durable foundation for a compatible AR-15 upper build.

5.56 NATO Chamber with 1:7 Twist

This BCM barrel is chambered in 5.56 NATO and uses a 1:7 twist rate. Its 16" length and government profile offer a practical balance for a wide range of compatible AR-15 applications.

Chrome-Lined 41V50 CMV Steel Construction

Made from 41V50 chrome moly vanadium steel, the barrel features a chrome-lined bore and chamber to help resist fouling and corrosion over long-term use. The manganese phosphate exterior finish provides added protection for the steel barrel surface.

Mid-Length Gas System and .750" Gas Journal

The mid-length gas system is paired with a .750" gas block journal, allowing use with compatible .750" gas blocks and mid-length gas tubes. The gas seat is dimpled to support precise gas block installation.

Government Profile with M4 Feed Ramps

The government barrel contour balances handling and durability, while M4 feed ramps support reliable feeding when used with a compatible upper receiver and bolt carrier group. A 1/2x28 muzzle thread pattern accepts compatible muzzle devices.

High-Pressure Tested and Magnetic Particle Inspected

BCM proof loads its barrels to 70,000 psi before magnetic particle inspection, helping identify potential surface flaws before the barrel is put into service.
