Bear Creek Arsenal "Caliburn" AR-15 10.5" 450 Bushmaster, Carbine Gas, Hbar, 1-24T Parkerized Barrel
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-15Pistol barrels can be chambered in a variety of different calibers, spanning from rifle to pistol cartridges. Thanks to the modularity of the AR-15 platform, your next pistol will be incredibly easy.
About This Barrel: The Barrel is made by Bear Creek Arsenal it is 10.5" long, and is machined from 4150 Chrome Moly Vanadium and finished in a Phosphate appearance. Chambered for .450 Bushmaster, using an 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: Pistol
Length: This Barrel is designated as a pistol length barrel with an overall length of <Length">.
Caliber: .450BM - This barrel is chambered for .450 Bushmaster, a big-bore hunting cartridge with the goal of providing one-shot kills at long range. .450 Bushmaster runs reliably in the AR-15 platform when paired with other correct components.
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: Phosphate - Manganese Phosphate finishes are used on barrels to protect against corrosion and wear. Manganese Phosphate finished is considered for its toughness, and is used in multiple different applications such as aerospace, ordnance, and other firearms-related parts.
