If you are looking to take advantage of the .300 blackout ballistics out of a long barrel, this 16” barrel from Ballistic Advantage is a great choice. The .300 BLK bullet was designed to be subsonic and shot suppressed for an extremely quiet and fun gun to shoot. However, shooting supersonic bullets will allow for better terminal ballistics and combined with the longer barrel, make for a great hunting rifle. This Modern Series barrel is made from 4150 chrome moly vanadium steel and has a quench polish quench nitride coating that is extremely corrosion resistant and easy to clean. It features a 1:7 twist rate that is optimal for stabilizing the heavy .30 caliber bullets and a pistol length gas system for reliable function. The gas block comes in at .750” to accommodate a large variety of adjustable gas blocks or standard gas blocks. The 5/8x24 thread pitch on the barrel allows for the attaching of muzzle devices such as flash hiders, muzzle brakes, or suppressors so you can further customize your setup. This .300 blackout barrel is a great option for building an extremely quiet carbine that is great to take on hog hunts or other various game.

  • Great option for suppressed hunting
  • 1:7 twist rate for stabilizing heavy subsonic 30 cal. bullets
  • QPQ Nitride finish for corrosion resistance
  • M4 feed ramp barrel extension
  • Threaded for .308 and 7.62 muzzle devices or silencers
  • Pistol length gas system
  • Guaranteed sub MOA accuracy with match grade ammunition
  • High pressure tested and magnetic particle inspected

Every barrel that leaves the Ballistic Advantage assembly line is high pressure and magnetic particle inspected to ensure every dimension is in spec. They are inspected because they believe in providing customers with a barrel that can shoot one-inch groups at 100 yards.

Ballistic Advantage proudly produces quality AR barrels that exceed very stringent demands. Their AR-15 barrels surpass the competition in precision and aesthetics. For barrels that deliver round after round consistently and accurately, choose Ballistic Advantage.
