Great idea. terrible fitment - AIM Sports Inc Featureless AK Pistol Grip W/Fin Backstrap

I purchased this to replace my current grip and have heard a lot of good things about this featureless grip... Well, for me, the fitment sucked!! First of all i couldn't get the screw that it came with to go in. No biggie. I'll just use the one from my current grip. Well after installing it, the grip wiggled quite a bit that I thought i was going to bend my spring. I grab my screwdriver and tighten that b*** until it didn't turn anymore... same thing! So I decide to give the screw it came with another go. After a few tries it finally grabs the threads but it seems tight, too tight in fact so i take it apart.... The dam* screw was stripping the threads on my receiver. This thing is going in the trash or maybe i'll try on another build but as of right now this gets 2 stars for effort.
