Have a Bergara Extreme Hunter stock on a back up rifle for coyote hunting. Want to put a SMALL arca rail on it for use on a tripod. The stock ("molded synthetic stock is made of glass fiber reinforced polymer") is skeletonized with a rib up the middle so can't mount the rail 'in-line' without wiping out that rib.

Any reason I can't mount the rail sideways (90 degrees) so I can straddle the rib?
