Manufactured by Geissele Automatics
The Geissele Automatics Reliability 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.
