ELD Performance 16" 5.56, Mid Gas, 1:7T, Government Profile, 4150-SR, Nitride, 1/2x28 Threads
General Barrel Info: The barrel on an AR-15 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 Government, 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 barrel is 16-inches long and made from 4150 steel with a nitride finish to improve its strength and longevity. It is chambered in 5.56 NATO and has a 1:7 twist rate. This reliable barrel has a Government profile and operates on a mid gas system.
Barrel Classification: Rifle
Length: This Barrel is designated as a pistol length barrel with an overall length of 16".
Caliber: 5.56 NATO - 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: 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.
