Ballistic Advantage AR-15 18" 6MM ARC, 1:7T, Premium Series, 5/8x24 , 
.750" Gas Block Journal  416R Stainless Steel Bead Blasted Barrel

General Barrel Info: The barrel on an AR-15 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 Government, 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: Ballistic Advantage produces quality AR barrels that exceed the most enduring demands of our customers. All Ballistic Advantage AR barrels surpass the competition in accuracy, precision, and beautifully contoured aesthetics. The engaged team of engineers and machinists continually improve designs and create innovations to enhance performance, from our popular 16" AR barrels to all other lengths and styles provided to produce the best functioning ARs available.

About This Barrel: This Barrel from Ballistic Advantage is 18-inches long and chambered for 6MM Arc. This SPR rifle-length barrel has a 1:7 twist rate and is crafted from 416R stainless steel with a bead blasted finish. This barrel is in the Ballistic Advantage Premium Series which means it features a nickel boron coated extended M4 feed ramp extension.

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 16" length.

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: 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: Bead Blasted - Bead Blasted finishes come out of the blast furnace with an incredibly strong and resistant exterior. Bead Blasted barrels result in a nice smooth matte finish.

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.
