get a sling swivel stud and mount it to the underside of the gun like 2.5 inchs from where it starts to thin out into that thick chunky wood. I just got some studs today and going to do this to my beater mosin because i can. I want a bipod on my mosin, looked at the clamp ons and decided NAYYYYYYY.... i saw a vid on You Tube of a guy doing this with the swivel stud and bipod. He said he had it at the range and held great, I think that is the best option, unless you're a purist hahahaahah . Mosin's didnt come with sling swivels. hahahaha If i ever get a nicer one i'll keep er stock and put pics up when i can
