I have a stock Ruger M77 MKII that I bought when I was 16, 25 years ago. It is not the rubberized paddle stock, but the hollow synthetic. The sling stud on the foregrip pulled out years ago and I've fixed it with epoxy now a couple of times. I've found that since I started using a bipod that those fixes done hold anymore. I'm trying to figure out the best way to reinforce the front end of the stock and I'm looking for advice. I've considered inserting a block of some form in there and epoxying it into place. I've also considered just adding a picatinny rail to it. Does anyone have any thoughts or experience they'd be willing to share?
