Recoil Technologies AR-15/AR-9 9mm Luger Bolt Carrier Group
Hybrid - Round Profile, External Extractor, Nitride, Black
An AR-15 9mm 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 9mm bolt carriers, the bolt head is flat and is critical in creating a seal on the blow-back design of AR-15 9mm Pistol Caliber Carbines.
About this BCG: This 9mm BCG Hybrid-Round Profile BCG is a premium component you should add to your next build. It is made from 416R stainless steel which is high-strength and incredibly durable. The nitride finish helps improve lubricity, corrosion resistance, and carbon resistance. It takes the classic BCG design and elevates it.
Caliber Compatibility: 9mm Luger (9x19) - This BCG is designed for the 9mm caliber. The most common pistol cartridge in the United States.
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 to heat, and corrosion.
Material: 416R Stainless Steel - Body - 416R SS is a hardenable chromium stainless steel particularly suited for use in high-quality 9mm Bolt Carriers. This grade has good machinability and, great resistance against heat and shock forces.
