OCKS screws by M-GUNS are optimized to provide more engagement with the gas key after staking to ensure they never come loose.
OCKS screws by M-Guns (set of 2)
These Grade 8, US Made screws have been modified with extra notches along the top edge to allow material from the gas key to better engage with the head after staking.
Gas key installation procedure:
We recommend lightly lapping the surface of the gas key with a stone and honing oil to remove any burrs and ensure a flat gas key.
Clean/degrease surfaces and apply Permatex or Loctite 620 bedding compound around the gas port on bolt carrier.
Oil threads and torque to 58 in/lbs
Stake gas key with a press type staking tool such as the M-Guns MOACKS.
Check bore with a .080 diameter weed eater line to ensure no sealant has creeped into the gas port after installation.
