Building a reliable 300 Blackout pistol or SBR just got easier with this barrel offering by Bravo Company USA. This BCM barrel was designed for optimal performance with the .300 AAC BLK cartridge. However, there is a large variety of .300 BLK ammo out there and Bravo Company recommends using a standard carbine buffer with subsonic ammo or an H3 buffer with high velocity ammo. The BCM 300 Blackout barrel features a continuous taper that helps to decrease weight at the muzzle making your rifle balance extremely well. In addition to the taper, the rear of the barrel is fluted to increase strength and heat dissipation for those long range sessions. With a pistol length gas system and a dimpled .750” gas seat shelf, you can experience the reliability that is known of Bravo Company USA. This short 12.5” AR barrel is a great option whether you want to build a pistol for the range or a short barreled rifle for home defense.

  • 12.5” 300 BLK chamber with pistol length gas system
  • 1:7 twist rate for stabilizing the heavy .30 caliber bullets
  • Chrome moly vanadium steel with phosphate finish
  • Chrome lined bore and chamber
  • Fluted and tapered profile
  • 5/8x24 threads for your favorite muzzle device

  • Carbine buffer with subsonic ammo or H3 buffer with high velocity ammo

Another popular term thrown around when talking about barrels is chrome lined bore and chamber. This process is used to create a surface that is harder than the cmv barrel steel. The main point of this is not to increase accuracy but to increase reliability. The hard surface aids in extraction, chambering, and reduces fouling and corrosion, resulting in an extremely long barrel life. The outside of the barrel is also parkerized with a manganese phosphate finish that facilitates oil absorption providing extra resistance to corrosion.
