Rifle on top reminds me of the Savage combos.  And I have one of these and like it.  But, I have a Tikka .222/12ga with the exposed hammer.  The 12 ga is on top with the .222 underneath.  I like the way it balances, the wider sight ramp, and personally the looks of it better.  I have a German Simson Suhl S X S 16ga X 25-35 cape gun.  Now, that I love.
