You can also cut or grind out the front of the spacer block in the front of the magazine. I drilled out the rivets holding it in place and used a hacksaw to cut the front piece out, dressed the sides up with a file and epoxied them back in place. Justr another option.
Shortgrass,
I had the front stud break off on a H-S Precision stock while using a bipod. I was able to repair it by epoxying an aluminium spacer from the threaded insert in the stock flush with the surface of the stock. This gives the swivel stud a solid shoulder to bear against.
Good luck...
