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 as from Government, to Heavy, and Slim. Thanks to the modularity of AR-15, 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 This Barrel: This 7.62 x 39 barrel is a medium profile barrel with a black nitride finish. The medium profile of the barrel gives you the accuracy you would expect from a heavy barrel but with some weight reduction so it isn't too heavy for hunting or competition shooting. The profile also helps with accuracy by reducing barrel whip as well as adding some weight up front which helps keep your muzzle down and on target. Since the surface of the steel is hardened during the nitride process, this barrel will last a lifetime. The 7.62x39 is one of the most common rounds in the world making it one of the easiest and most affordable rifle cartridges available. This barrel is a great way to enjoy the hard hitting, and really fun AK round on the AR-15 platform.
About the Profile: Medium - Medium Profile barrels are designed to have an even weight distributed from the beginning to the end of the barrel, this results in a rather tubular looking appearance but with identical rigidity and properties to a government profile barrel.
