ELD Performance 18" 6MM ARC, Rifle Gas, Medium Profile, 1:7.5T, Nitride Barrel
General Barrel Info: The barrel on an AR-15 originally operates under a 'gas impingement' system' by tapping gas off of the barrel and cycling it back through the gas system to assist the bolt carrier in unlocking and extracting the spent cartridge. AR-15 Barrels come in four different specifications for gas systems, Pistol, Carbine, Mid-Length, and Rifle. AR-15 Barrels vary between profiles as well as from Government, to Heavy, and Slim. Thanks to the modularity of AR-15, you can choose different calibers starting with the barrel, each with its specific twist rates. Choosing your barrel for your next AR-15 build has never been easier.
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.

Caliber: 6mm ARC - 6mm ARC is a rifle cartridge introduced for the AR-15 Platform in 2020, as a low-recoil, long-range, and high accuracy cartridge. 6mm ARC uses a 6.5 Grendel Bolt Carrier to operate in an AR-15.
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: 5/8x24 - 5/8x24 Threads are commonly found on barrels chambered in .30 Cal and up. Usually .308 Win, .300BLK, 6.5 Grendel, 6.5 Creedmoor, and 7.62x39. Muzzle Devices such as flash hiders, blast cans, and compensators will work with this barrel.
