ELD Performance AR-15 4.5" OAL 9MM, Medium Profile, 1:10T, 4150 CrMoV, 1/2x36, Nitride Barrel

General Barrel Info: The barrel on a 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 barrels come in two gas lengths, Pistol, Carbine, & Mid-Length. Pistol barrels can be chambered in a variety of different calibers from rifle to pistol cartridges. Thanks to the modularity of the platform, your next pistol will be incredibly easy.

Brand Info: The Engineers at ELD Performance have created a line of high-quality barrels precision machined for reliability and accuracy at an affordable price! ELD Performance barrels are made in a variety of calibers with the reliability to rival the best.

About This Barrel: This high-strength barrel is 4.5-inches long and chambered for 9MM. It has a medium profile with a 1:10 twist rate. It is made from high-strength 4150 CMV with a black, nitride finish that keeps it resistant to corrosion. This barrel has been designed to be reliable and accurate on even the craziest of adventures.

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 4.5".

Caliber: 9mm - This barrel is chambered in 9mm, perfect for light recoiling pistol caliber carbines or rifles. 9mm is the most popular pistol cartridge in North America.

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: 1/2x36 - Commonly found on barrels threaded for 9mm, this will allow for 9mm muzzle devices on your AR-15 platform.
