General Barrel Info: The Barrel on an AR-15 pistol operates through a 'gas impingement' system, where gas is tapped from off from the barrel and cycle back through a connected gas system, to help the bolt carrier in unlocking, and extracting a spent cartridge. Pistol length AR-15 barrels come in two gas lengths, Pistol, Carbine, & Mid-Length. AR-15 Pistol barrels can be chambered in a variety of different calibers, spanning from rifle to pistol cartridges.

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: Pistol
Length: This Barrel is designated as a pistol length barrel with an overall length of 8".
Caliber: .300BLK - This barrel is chambered in .300 Blackout, a modern intermediate rifle cartridge developed for reliability under sub-sonic and super loads through a suppressed or unsuppressed barrel configuration. .300 Blackout is the Western counterpart to Russian 9x39 Rifle Cartridge. .300 Blackout is an ideal cartridge for hog hunting, shooting suppressed with sub-sonic ammunition, and home defense due to improved stopping power.
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.
