Bravo Company Manufacturing 5.56 NATO 1:7 Mid-Length Government Profile AR-15 Barrel – 14.5"

Bravo Company Manufacturing 5.56 NATO 1:7 Mid-Length Government Profile AR-15 Barrel – 14.5"

The Bravo Company Manufacturing 14.5" AR-15 barrel is a durable, mil-spec-oriented option for builders seeking a balanced 5.56 NATO barrel with a mid-length gas system. Made from 41V50 chrome moly vanadium steel, chrome lined, and manganese phosphate finished, this BCM government-profile barrel combines practical weight, corrosion resistance, and proven AR-15 component compatibility.

5.56 NATO Chamber with 1:7 Twist

This barrel is chambered in 5.56 NATO and uses a 1:7 twist rate. The 14.5" length and government contour make it a strong choice for compatible AR-15 builds where a balanced barrel profile and mid-length gas system are preferred.

Chrome-Lined Bore and Chamber

The bore and chamber are chrome lined to support long service life and corrosion resistance. A manganese phosphate exterior finish provides additional protection for the barrel’s steel construction in demanding shooting and environmental conditions.

Mid-Length Gas System and .750" Gas Journal

A mid-length gas system is paired with a .750" gas block journal, allowing the barrel to accept compatible .750" gas blocks. Confirm gas block, gas tube, handguard, and muzzle-device compatibility before completing your build.

Government Profile with M4 Feed Ramps

The government barrel contour offers a familiar balance of weight and handling characteristics for AR-15 builds. M4 feed ramps support reliable cartridge feeding when paired with a compatible upper receiver and bolt carrier group.

High-Pressure Tested and Magnetic Particle Inspected

Each barrel is high-pressure tested and magnetic particle inspected to help verify structural integrity before it reaches your build bench.
