I had a buddy that had a buddy that had a Magpul grip break off at the screw head and the grip just came off in his hand. I went to my stash of parts and looked at the thickness around the hole where the bolt goes through and it's much thinner than most other grips that I had around to compare it to. I swapped out the grip and re-installed a regular old grip on my 308AR rifle until I can find a better solution to making sure the Magpul grip doesn't crack off on one of mine. I'm sure that Magpul made the grip thinner in that area so that it allows longer items to be stored in the grip but how thin is acceptable? Perhaps a custom metal plate that fits between the screw head and the plastic grip to distribute the weight over a broader area to keep it from cracking?

You mean a washer?
Yeah, those are in standard grips. What'd your buddy's buddy do? Whack it with a BFH? Never heard of this before.

Re: Magpul grip
Well of course the lock type washer is there but what about a long oval shaped plate to match the whole floor of the grip. I like using the Magpul grip for two reasons: it moves my hand back a bit for better position on the trigger and it has a very well designed storage compartment.
No idea if he torqued down the screw WAY too tight or smacked the heck out of it against something...

Re: Magpul grip
I think that the breakage your friend of a friend of a friend of a second cousin's former roommate (
) experienced is the exception to the rule as far a durability and dependability of the Magpul grips go. I have literally beat the hell out of several MIAD grips in various classes on AR-type rifles from 9mm carbines to 308 AR-10s without issue. I have also watched as others abuse the hell out of their Magpul grips without issue.
One note...overtightening a metal screw against an aluminum receiver sandwiching a polymer part in the middle will almost 100% of the time lead to a failure of the polymer part. Something has got to give there and it isn't likely going to be the receiver or the grip screw. Also, Magpul supplies a pan-head screw with some form of blue loc-tite pre-applied to it that has a larger bearing surface than the standard screw. They advise against using the standard factory screw and lock washer.
If you don't have faith/confidence in them...by all means ditch yours and find something else that will put your mind at ease. Nobody should be running gear that they don't trust. BUT, if you install the grip properly, with the proper screw and you don't go gorilla on the torque, I think you will be fine.

Re: Magpul grip
-Lonestar, I am your father's cousin's second uncle's former roommate.
-So what's that make us?
-Absolutely nothing!
Spaceballs, I love that movie!
Oh, and by the way. He tightened the grip too much. I learned the hard way with that one. Put a large washer in it and it'll be fine.

Re: Magpul grip
I also agree that he probably went gorilla on the screw but wanted to know if anyone else might have had this happen to them. I do use the flathead screw that Magpul provides so I know that it is larger than most of the screw heads that you normally see.

Re: Magpul grip
Is there a torque value for this or is it just a use the force type of deal?
Also thanks for that Keith great movie

Re: Magpul grip
There is no specific torque value for the grip screw when mounting any Magpul grip. Magpul's advice is "hand tighten" which I have always taken to mean "snug" it down and let the loc-tite do its thing. No need to go crazy tightening it down.
