It's important to note that the gas key on this bolt carrier group is non-staked, as per the manufacturer's recommendation. The decision to not stake the gas key is based on the fact that staking only prevents the screws from backing out and does not aid in sealing the gas key. By not staking the key, you have the flexibility to properly torque the screws to 35 inch pounds, thereby reducing the risk of loose or broken screws.

Included in the package are a complete carrier, bolt, cam pin, firing pin, and firing pin retaining pin, ensuring that you have everything you need for a seamless installation.
