Brownells Lightweight Carbine Barrels are available in various lengths to cater to any new carbine build. They are made from 4150 Chrome Moly Vanadium steel and manufactured to Brownells standards by Rosco Manufacturing. These button-rifled barrels come with a 223 Wylde chamber that accommodates 223 Remington and 5.56x45mm NATO ammunition equally. The slim profile of these barrels is due to their .625 gas block journal, which prevents the Carbine from becoming front heavy. Additionally, the barrels have ½-28 muzzle threads that accept common muzzle devices and M4 feedramps that interface perfectly with M4 feedramps in your upper receiver. The 1-8 twist can handle Full Metal Jacket 55gr loads and heavier, premium 77gr bullets without any problem. Lastly, the Nitride finish ensures that these barrels resist corrosion, enable easy cleaning, and have an extra hard surface to prevent dings and nicks. Rest assured, Brownells offers a lifetime guarantee to the original purchaser of these Lightweight Carbine Barrels.
