OK I've always used Harris Bipods on a sling swivel stud, but you guys are always posting up pics of Atlas, or GG&G pods (so naturally, now I want one). So I go to shopping, and well it looks like both of those brands require a spigot, or 1913 rail to mount on. Is there a way to mount those bipods on a sling swivel stud? I'm probably overlooking something, as I'm unfamiliar with the ins and outs of them.
