This kit comes with everything you need to take your AR-15’s performance to the next level, including the enhanced 5.56 BCG, Super 42 braided buffer spring, and H2 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. With this kit, you can rest assured that your AR-15 will be running at peak performance for years to come.
