ELD Performance AR-15 10.5" 5.56 NATO Front Sight Base Barrel w/ Front Sight Assembly and Carbine Gas Tube

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: Looking to start a new retro AR-15 Pistol? New to Delta Team Tactical, this 10.5-inch Front Sight Base Barrel operates on a carbine gas system and has a 1:8 twist rate. It is crafted from 4150 CMV with a high-strength black nitride finish. It features an A2 F-Marked Base Gas Block and a round handguard cap and also includes the A2 Delta Ring Assembly for quick installation for drop-in handguards. This barrel will make a great addition to your next 5.56 NATO build.

About the Profile: M4 - The M4 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: 5.56 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: 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.
