The Brownells Premium Lightweight Carbine Barrels offer a durable and high-quality option for building a new carbine. These barrels are available in several popular lengths to suit your specific needs. Ballistic Advantage manufactures these barrels to Brownell’s high standards, ensuring you get the best product possible. The exterior of the barrel features a standard phosphate finish that not only provides an excellent matte finish, but also retains oil extremely well. The bore and chamber, the most important aspect of the barrel, are hard chromed to prevent corrosion, make cleaning easier, and prevent long-term wear.

The button rifled barrels are made from 4150 Chrome Moly Vanadium steel and feature a 223 Wylde chamber that can accommodate 223 Remington and 5.56x45mm NATO ammunition equally well. The 1-8 twist can handle Full Metal Jacket 55gr loads and heavier, premium 77gr bullets. All of the Lightweight Barrels have a .625 gas block journal to correspond with the slim profile and prevent your Carbine from becoming front heavy. Additionally, the ½-28 muzzle threads accept common muzzle devices and M4 feedramps at the opposite end interface perfectly with M4 feedramps in your upper receiver.
