Looking for a fast handling, lightweight barrel configuration? Check out Brownells Lightweight Carbine Barrels. These barrels come in a variety of popular lengths to suit all kinds of carbine builds. Manufactured according to Brownells specifications by Rosco Manufacturing, these barrels are button rifled and profiled from 4150 Chrome Moly Vanadium steel. They feature a 223 Wylde chamber which can handle 223 Remington and 5.56x45mm NATO ammunition equally well.

With a 1-8 twist, these barrels can handle Full Metal Jacket 55gr loads, as well as heavier 77gr bullets. The .625 gas block journal matches the slim profile, keeping your Carbine from becoming front heavy. They also have ½-28 muzzle threads which can accept common muzzle devices and M4 feedramps that interface perfectly with M4 feedramps in your upper receiver. Moreover, the Nitride finish of these barrels prevents corrosion, eases cleaning, and has an extra hard surface that prevents dings and nicks.
