Probably a stupid question but what's new? I have an AR with a metal hand guard and a wood stocked bolt gun that only have the sling stud on which to mount the related bipods. I want all my guns to be able to work with my Altas bipod that uses a small pic rail. I am wondering if I need to drill another hole in both of these stocks to attach a two holed pic rail or if there is a suitable adaptor out there? I am trying to find something that doesn't have another sling stud protruding that will interfere with my Atlas. Also wondering if one screw is sufficient to handle mounting my Atlas bipod to a 10-12lb. gun?
