I apologize in advance to the mods if this is posted in the wrong subforum ( please move to the appropriate subform if possible ). I have seen a few mods to MagPul MOE grips that involve silicone, RTV sealants, super glue, electrical tape and other mods. But if you’re looking for a cleaner solution that can be undone without any trouble you may want to try the O-ring mod.
Parts and tools needed for the job.
(2qty) 6.8X19mm {P7} o-rings
a small file

Step 1.
Use the file to make two small notches on each side of the MOE grip core cover. They do not have to be very deep, just enough to keep the o-rings from sliding off during installation and removal of the core cover. Try to make the notch as close to the center as possible. ( This step is optional, you can slide the o-rings on over the edges of the cover but the nocks or notches keep them in place when you need to access the grip core. )


Step 2.
Install the o-rings onto the core cover.

Step 3. You’re done, now snap on the cover. The core cover is now very secure and will not rattle.
