ELD Performance "Grumble" AR-15 8.5" 9mm, 4150 CrMoV, 1-10T, Nitride, 1/2x36, Barrel
General Barrel Info: The barrel on a 9mm AR-15 barrel operates under 'direct blowback' there is no gas system directly connected to a 9mm AR-15 barrel for the system to cycle. By design 9mm AR-15 barrels are affordable and come in many sizes, rifle, and pistol. This includes many of the familiar barrel profiles found on standard/common AR-15 platforms. Building an AR-15 chambered in 9mm is a great choice for training, or for your next Pistol Caliber Carbine build.
About This Barrel: The "Grumble" Barrel is made by ELD Performance it is 8.5" long, and is machined from 4150 Chrome Moly Vanadium, and is finished in a Nitride appearance. Chambered for 9mm Luger, using a medium profile design, this barrel will be a perfect choice for your next AR-15 PCC.

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.
