Brownells offers a range of Lightweight Carbine Barrels which are ideal for new carbine builds that require a fast handling and lightweight barrel configuration. These barrels are available in a selection of popular lengths and are manufactured to Brownells' specification by Rosco Manufacturing. They are profiled from 4150 Chrome Moly Vanadium Steel, using a button rifling process, and feature a 223 Wylde chamber which allows them to accommodate both 223 Remington and 5.56x45mm NATO ammunition equally well.

These barrels have a 1-8 twist and can handle a range of Full Metal Jacket 55gr loads up to premium 77gr bullets. The barrels have a .625 gas block journal which corresponds with the overall slim profile to prevent the carbine from becoming front-heavy. The ½-28 muzzle threads accept common muzzle devices, and the M4 feedramps at the opposite end interface perfectly with M4 feedramps in your upper receiver.

The barrels are completed with a durable Nitride finish, which not only helps prevent corrosion but also eases cleaning whilst providing a hard surface to prevent dings and nicks. Customers can have full confidence in these barrels, which are accompanied by an original purchaser lifetime guarantee.
