The Geissele Automatics Reliability Enhancement kit comes with the enhanced 5.56 BCG, Super 42 braided buffer spring, and H1 buffer weight. The Enhanced Bolt Carrier Group is a full mass M16 profile full auto rated BCG built out of premium materials and coatings for long term durability and reliability. The carrier is machined from 8620 steel and the cam pin is machined from H13 steel. The entire AR-15 Bolt Carrier Group is coated in Nanoweapon which is a Chrome-Nitride finish that increases smoothness and surface hardness for corrosion resistance and cleaning. The carrier also features longer upper rails to prevent carrier tilt and increase feeding reliability. The bolt is forged from Carpenter 158 steel and undergoes a proprietary heat-treating process that reduces impurities and makes it stronger and more consistent than other C158 bolts. Additionally, each bolt undergoes high pressure testing, magnetic particle inspection, and a rigorous inspection process. If you are looking for an AR-15 5.56 Bolt Carrier Group that will last a lifetime, you can’t go wrong with the Geissele Automatics Enhanced BCG.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.
