ELD Performance AR-15 7.5" 5.56 NATO, Pistol Gas, 1:7T, Nitride, 4150 CMV, 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 barrel is 7.5-inches long and operates on a pistol gas system. It is chambered in 5.56 NATO and has a 1:7 twist rate. It is made from 4150 CMV which is tough and the nitride finish keeps it resistant to corrosion.
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.
Barrel Classification: Pistol
Length: This Barrel is designated as a pistol length barrel with an overall length of 7.5".
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.
