I recently acquired one of the little Browning OU double rifles in .270. Someone had a elegant quarter rib and claw mounts installed, but that is a story for another day. My question is, would anyone have any ideas about getting a set of 20 ga barrels and forearm fitted? I am having a hard time trying to get my ahead around trying to find a "clunker" superposed from which to use the barrels. Would appreciate any thoughts on another solution.
