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.
