Magpul Grip Screw?

Stupid things are the devil.

Could you provide maybe any amount of detail? What is stripped? The male threads? Female threads? Head of bolt? Is bolt installed and needs to be removed? Is bolt removed and you need to install it?

The 22lr m&ps have a plastic reciever,
the grip screw is prone to crossthreading and wallowing out the threads if the owner decides to get curious

Note to self: Don't fuck with the M&P15-22 factory grip

Thanks for the heads-up

Thanks everyone for the feedback. I removed the grip when I received the rifle, to install a drop in trigger. Put every thing back together. Then I went to range to shoot it. Also to test out my new Awesome Trigger, Rise Armament, if anyone cares to know. Well then all went great. Then, after about 100 rounds. I noticed the grip was loose, and was about 1/8" of an inch away from the bottom receiver. Seeing the grip spring loose, the spring that holds the safety detent spring!! So I went back home to tighten screw, thinking.. well maybe I just did not tighten it enough. That's when I found that the grip screw kept spinning, upon trying to retighten grip screw. So then I removed the screw, and found little plastic pieces coming out, more like whiskers from a one day shave. But hardly nothing to be alarmed about.

So then I thought, by how tight the grip screw was when first starting to screw it into the hole. The answer would be to add washers to the OEM grip screw. Making the grip screw shorter, and that would fix my problem. That did not work. So here I am today. What an Awesome Rifle, besides this problem. This could be fixed from the factory in the future, using a molded in steel block inside the lower plastic receivers where the grip screw would go.

Thanks doc. Problem fixed. Also a BIG... Thanks to every one for your replies.
