Yes Sir Steve I have, don't know if you have ever done any work on a Hi-Point but IT BE ALOT WORSE. A lot of honing, sanding, polishing, WOW.

SEE YOU GET IT ( FUN ) by doing some clean up work on these lower priced guns to make them better, not every gun is the same. As you said, IF U HAVE THE KNOW HOW, KNOW WHAT TO DO & WHERE. It's a TOTALLY DIFFERENT GUN & STILL SAFE.

About the epoxy, I don't buy the 15 minute epoxy, there is many kinds of devcon, the stuff I use sets up in about 6 hrs. cures in 24 or so ? You can sand it, file it, drill it, thread it, mold it ect...

I bed rifles with it, the J-B weld shrinks too much for that but it is GREAT STUFF.
