ELD Performance 10.5" 5.56, 1:7T, Carbine Gas, Government Profile, 4150-SR, Nitride Barrel

General Barrel Info: The barrel on an AR-15 pistol operates through a 'gas impingement' system, where gas is tapped from off the barrel and cycled back through a connected gas system to help the bolt carrier extract a spent cartridge. Pistol length AR-15 barrels come in two gas lengths, Pistol, Carbine, & Mid-Length. AR-15 Pistol barrels can be chambered in a variety of different calibers from rifle to pistol cartridges. Thanks to the modularity of the AR-15 platform, your next pistol will be incredibly easy.

About This Barrel: This 10.5-inch barrel operates on a carbine gas system and is chambered for 5.56. It has a 1:7 twist rate which works well to stabilize heavier projectiles. It is made from high-strength material with a nitride finish to ensure it is durable, reliable, and incredibly strong.

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.

Barrel Classification: Pistol

Length: This Barrel is designated as a pistol length barrel with an overall length of 10.5".

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: 4150 CrMoV - Chrome-Moly Vanadium, or simply "CMV", is the official mil-spec gun steel developed by Colt Firearms for the military-issued M16 and M4. It contains the same elements as 4150 steel. It also contains Vanadium. Vanadium significantly increases the strength, hardness, and high-temperature stability of the steel.

Finish: Nitride - Nitriding is a process during manufacturing that diffuses nitrogen into the steel to make a case-hardened surface for improved resistance and strength. A Nitrided barrel typically has a gloss black texture.

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.
