To provide superior mounting for your grips, use these O-rings around the grip screw in conjunction with bushing O-rings and Hex Drive Bushings.
For the best possible grip stability, combine O-rings around your screws with Hex Drive Bushings and Bushing O-rings for superior mounting. This system will lock your grips firmly into place so they won't shift during firing; thus effectively preventing any loosening of grip screws. Unfortunately, these rings get worn out quickly due to the force exerted on them while shooting - we recommend having backup pairs handy at all times!
