Well, last night, the screw that the bipod mounts to popped right out, it just stripped itself out of whatever composite the stock is made of. When the bipod came off, I saw this is the third hole, so the previous owner had the same issue.
My question is, if I bought a hogue overmold with the swivels already attached, how deeply/securely are they mounted? The screw I had was only 1/4" and now im nervous about getting another composite stock and having it rip loose again over time.
I had a 10/22 Hogue overmold stock, and used it with a Harris bipod quite regularly with no problems at all. However, I'm also fairly careful not to ovetighten the mounting screw, as it exerts considerable force on the swivel stud, and can lever the stud out given time and a few impacts.
As vafish said (above), the machine-screw swivel with round knurled nut is a more secure system, but if there is not room between the inside stock surface and the barrel, the nut will have to be countersunk into the forend, and you also might have to shorten the screw. I bought a 12-pack of these swivels about 10 years ago, and I'm still working my way through them.
Finally, if there is a shallow hollow area in the forend, you might be able to use a #2 or #5 adapter. These are basically the same machine-screw swivel, but the nut is attached to a backer bar to spread the force inside the forend, preventing pull-through problems. This is what they look like:
I've used these on many different type of stocks and forends (including AR-15 free-float tubes with stripped-out threaded holes, and synthetic thumbhole stocks with relatively thin forends), and never had one pull out.
