Introducing the Brownells Premium Lightweight Carbine Barrels - a premium barrel configuration designed for hard use. These barrels come in different lengths to cater to any new carbine build. The manufacturing of these barrels is supervised by Brownell's quality standards and produced by Ballistic Advantage to ensure that you get the best barrel possible. The barrel's exterior is covered with a phosphate finish, providing an impressive matte appearance and keeping oil well retained. However, the most significant part of these barrels is the hard chrome bore and chamber that prevents corrosion, simplifies cleaning, and provides long-term wear resistance. These button rifled barrels are profiled using high-performance 4150 Chrome Moly Vanadium steel, with a 223 Wylde chamber capable of accommodating both 223 Remington and 5.56x45mm NATO cartridges. The 1-8 twist can handle a wide range of commonly available Full Metal Jacket 55gr loads as well as heavier 77gr premium bullets. The slim profile of all Lightweight Barrels has a .625 gas block journal, preventing your Carbine from being front heavy. Additionally, the barrels have 1/2-28 muzzle threads that are compatible with common muzzle devices, and M4 feed ramps that mix perfectly with M4 feed ramps in your upper receiver.

At Brownells, we stand behind our products and offer an original purchaser lifetime guarantee. Trust us and have confidence in the Brownells Lightweight Carbine Barrels for your next carbine build.
