^I've used one of their bipods before on a mosin nagant that had the ATI stock on it, was the model that uses the swivel stud. I will say that it held up well, over 250 rounds with that beast and the bipod never gave me any trouble, I doubt a million rounds through a 22 would be as abusive as that 7.62x54 was. I think I may just grab one of those for my 15-22, been looking for a bipod, since I like shooting from a bench.
In fact, if you have a Prime account, here's the same one for $25 shipped
