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 scientists and engineers have been hard at work in the workshop and laboratory creating AR products that are out of this world. The result of this brain trust is a firearms brand simply known as Mercury Precision. The goal with Mercury Precision was to create high-end products that do not require a space travel budget to afford.

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.
Barrel Extension 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.
