General Barrel Info: The barrel on an AR-15 originally operates under a 'gas impingement' system, by tapping gas off of the barrel and cycling it back through the gas system to assist the bolt carrier in unlocking and extracting the spent cartridge. AR-15 Barrels come in four different specifications for gas systems, Pistol, Carbine, Mid-Length, and Rifle. AR-15 Barrels vary between profiles as well from Government, to Heavy, and Slim. Thanks to the modularity of (AR-15/LR-308), you can choose different calibers starting with the barrel, each with its specific twist rates. Choosing your barrel for your next AR-15 build has never been easier.

About the Profile: Government - The government barrel profile is lightweight under the handguards, until just before the gas port. After the gas port, it gets heavier, out to the muzzle.

Length: This Barrel is designated as a rifle barrel with an overall 16" length.
Caliber: 5.56NATO - This barrel is chambered to fire both 5.56 NATO and .223 Remington, the most commonly used round designed for the AR-15 platform.
Material: 416R SS - 416R is a hardenable chromium stainless steel particularly suited for use in high quality precision rifle barrels. This grade has good machinability and, because of closely controlled chemistry and processing techniques, may be machined and lapped to a high finish, which is important for bore accuracy.
Finish: Stainless - Stainless steel finishes come in high-luster finishes similar to nickel plating, but with the added benefit of increased strength and corrosion resistance. Stainless steel finishes do not experience the same wear that other metals may experience such as peeling, flaking, wear and rust from scratches where the oxidation protection layer may be removed.
Thread Pitch: 1/2x28 - This threading is commonly found on barrels chambered in 5.56, .223, and .224. This will allow the installation of most muzzle devices such as flash hiders, blast cans, and compensators threaded to 1/2x28 threads.
