.458 SOCOM/.450 Bushmaster Complete BCG
An AR-15 bolt carrier group is a piece of a firearm that houses many key parts such as the firing pin, gas key, cam pin, extractor, and bolt. With all these pieces working together the BCG can grab and feed another round out of the detachable magazine chamber. During the extraction of a cartridge, the BCG works to absorb the force of the explosion by expanding gas in the carrier. Throughout this process, gas is tapped off from the barrel and sent into the cup inside of the gas key which creates an inertial force that sends the Bolt Carrier Group back into the buffer tube. This entire process helps to reduce recoil. For 450 Bushmaster/.458 SOCOM bolt carriers, the bolt head is larger to accept the larger diameter casing of .450 Bushmaster/.458 SOCOM Cartridges.
About this BCG: This bolt carrier group is for an AR-15 chambered in .450 Bushmaster or .458 SOCOM and has a nitride finish. This BCG is HPT tested/MPI marked. These BCGs are produced using the most precise milling and turning tools and equipment in the industry to instill customer confidence in the quality of the finished part.
Caliber Compatibility: .450 Bushmaster / .458 SOCOM - This BCG is created for the .450 Bushmaster / .458 SOCOM calibers, 2 big-bore cartridges originally developed from .50 Action Express. .458 SOCOM was designed to be used on the AR-15 Platform to deliver more ballistic energy on impact at supersonic speeds. ANd .450 Bushmaster was designed to be a more affordable big-bore cartridge designed for hog hunting.
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 BCG typically has a gloss black texture. Nitrided Bolt Carriers have increased resistance from heat, and corrosion.
Material: 9310 Alloy Steel - Bolt Head - 9310 Steel is a low alloy steel that is a mixture of nickel, chromium, and molybdenum. This steel is built to have high core hardness and high fatigue strength which make it the perfect steel to hold up in the harsh environments of the bolt head. 8620 Alloy Steel - Body - 8620 Steel is a carburized alloy steel meaning carbon was added to increase the hardness of the steel. 8620 is known for its high case toughness and high core toughness. Made mostly of nickel concentrate, this steel can easily withstand the firing stress of the BCG under operation.
Forward Assist Notches: This BCG comes with forward assist notches which allow the forward assist on the upper to contact the BCG pushing it forward and locking the bolt into place. These forward assist notches can also help clear malfunctions in a speedy manner when the BCG becomes jammed.
Gas System: Direct Impingement - Direct impingement is the process of directing the gas created during the operation of a firearm through the barrel, gas block, gas tube, and eventually into the BCG again to cycle the action and prepare the firearm for another round.
