I drilled a hole and because there wasnt much synthetic in there i filled it in with epoxy then whiped any that got on the stock off and let it set up. I put tape over the hole to keep the epoxy from oozing out onto the stock during the set up time. I removed the tape and redrilled the hole in the same spot. I then put a little epoxy in teh ole and put in the stud and wiped away any excess from the stock. My uncle had some kind of synthetic resin i used but JB Weld would work just the same. If the stock is 3/8in thick where you drill i would say you dont need the epoxy but i would use it or a strong glue to hold the stud.
