Then I threaded the hole with an M2 tap and then used an M2 3mm set screw with thread locker and also covered the hole. There is no way they are coming out even if I wanted to. I can weld the hole if I wanted. Pinning is probably the best method. 1 Quote Share this post Link to post Share on other sites

Since it's just an evil feature, it should be the same as pinning your stock. Anyone ever weld their stock or just blind pin? Quote Share this post Link to post Share on other sites

I always presumed JB Weld was a no-go, so was the cover done with a stick weld? Quote Share this post Link to post Share on other sites

I have the same on my one lmt, screw and threaded buffer tube. The welding part I threw in as rhetorical for effect, I know no ones welding their stocks in place :-) 14.5" barrel I'll have a friend thrown a quick weld on top. 16" barrel just some jb weld over the pin and then alumahyde coating so you can't see it.
