7.62x39 BCG, Nitride, Complete
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 7.62x39 bolt carriers, the bolt head is larger to compensate for the bigger diameter casing of the 7.62x39 Cartridges.
About this BCG: This 7.62x39 BCG is an AR-15 compatible BCG. This BCG is full-auto compatible and features forward assist notches to help unjam your firearm and allow it to function properly. This BCG is also MPI tested to give assurance that it can withstand the heat and pressure of your firearm without suffering structural damage. The 9310 and 8620 Alloy Steel also ensures the structural soundness of this BCG. This BCG comes with a nitride finish as well to give it the amazing look and slickness that you love.
Caliber Compatibility: 7.62x39 - This BCG is designed for the 7.62x39 caliber. The most common cartridge used in AK series of rifles.
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 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.
