I knew not to but did it without thinking. I should have used the PSA screw for the new grip but I used a Magpul supplied screw for the replacement AR grip. Now the PSA lower is stripped and I'm afraid I'll make it worse. I did attempt to screw it in from the top to see if I could re-thread it. However, the top hole is much smaller than the bottom. I googled and read a few ways to fix with a helicoil but I have 0 experience with it. Any of you done this before? If so, how did you fix it? Thanks for any and all help.
