My rifle came with a swivel and stud for the rear lower buttstock. The stud has threads as if it were designed to screw into wood(?) after a pilot hole had been drilled(?) (not machine threads like a bolt). Anyway, I can insert this stud about half way into the hole under the stock, but it will not thread in as you would expect, in fact it doesn't screw in at all.
I'm loathe to start drilling holes in things & hammering things I shouldn't be messing with, so before I do that maybe someone knows what the problem is?
Many thanks!
