General Barrel Info: The Barrel on an AR-15 pistol operates through a 'gas impingement system, where gas is tapped from off from the barrel and cycle back through a connected gas system, to help the bolt carrier in unlocking, and extracting a spent cartridge. Pistol length AR-15 barrels come in two gas lengths, Pistol & Carbine. AR-15Pistol barrels can be chambered in a variety of different calibers, spanning 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 made by ELD Performance it is 7.5" long, and is machined from 416R Stainless Steel and finished in a Stainless Steel appearance. Chambered for 5.56 NATO, using a Medium design, this barrel will fit your next AR-15 build perfectly.
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: 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.
