While puting together my lower receiver build from hell, I ran into yet another problem. While installing my MIAD grip, with screw provided from Magpul, into my Spikes Tactical lower, I was only able to get it a few turns in before it stopped completely.

Upon removing the grip screw, it appears that there is some cross threading in the hole for the grip screw on the lower receiver. I'm not sure if it was like that before or if I did it. I was not torquing hard on the screwdriver during installation. I have installed and removed pistol grips dozens of times without a single problem until now. Now I have 2 questions.

1. Is it possible that I damaged the lower receiver by cross threading the screw?

2. What do I do now to fix the problem so I dont have an expensive paperweight laying around my house?
