ELD Performance "Mark" AR-15 18" 6.5 Grendel, Mid Gas, Heavy Profile, 1:8T, SS Spiral Fluted 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 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.
About This Barrel: This "Mark" Barrel is made by ELD Performance it is 18" long, and is machined from 416R Stainless Steel and finished in a stainless steel appearance. Chambered for 6.5 Grendel, using a H-Bar profile design, this barrel will fit your next AR-15 build perfectly.
About the Profile: H-Bar - A heavy barrel adds a lot of weight to the rifle but a rifle thus equipped is more accurate than a rifle with a normal barrel because a heavy barrel heats up much more slowly than a normal barrel. With more material added, a heavy barrel by design is structurally stronger and more accurate.
Barrel Classification: Rifle
Length: This Barrel is designated as a rifle barrel with an overall 18" length.
Caliber: 6.5 Grendel - This barrel is chambered in 6.5 Grendel, a precision cartridge developed for the AR-15 platform, designed with superior long-range ballistics, and is a great middle-ground between 5.56 NATO and .308 Win in long-range performance.
Material: 416R SS - 416R is a hardenable chromium stainless steel particularly suited for use in high quality precision rifle barrels. This grade has good machinability and, because of closely controlled chemistry and processing techniques, may be machined and lapped to a high finish, which is important for bore accuracy.
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.
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.
