The OCKS (Optimized Carrier Key Screws) from Ned Christiansen of Michiguns is a massive upgrade to the standard gas key screws. The OCKS screws feature a heavy "spline" on the top edge of the head which mechanically engage the gas key after staking far stronger than the typical serrations found on milspec gas key screws. For the most secure installation of gas key screws, OCKS are the best option we've found to date, hands down.
Bexar Arms has been so impressed with OCKS gas key screws that we use them in ALL of our gauged and inpsected carriers!

OCKS gas key screws
The AR type rifle uses a gas system to function. The bolt carrier uses a gas key that is mounted on to the carrier using 2 screws. These screws must be properly installed and staked. The screws must be configured to ensure they don't back out causing the gas needed to load the next round and eject the spent round to escape. The screws I bought from BEXAR are EXACTLY the right screws to do the job. I bought 10 of them and actually changed out other screws that were not purpose built for the gas key assembly. They have performed flawlessly.
