Well, the Anschutz rail is 3" high, with a spread (from center of one foot to centre of other) of 4.5".
I think, unfortunately, that will be too low.
I'll call Fred at Choate today and see if he knows of a crafty solution.
Still love the idea of a bipod that has no moving parts and costs very little.
I had a Shooters Ridge (the ones at WalMart) and couldn't get it to hold tight so I returned it.
