Nice!And, I'd like to know the ring maker please, rarely see a 42 mm obj. 30 tube sit that low.
Bolt throw and eye piece mass, has a lot to do with how low you can mount the scope.
Have a Leupold 4.5x14 30mm mounted on the deck of a Rem .204, but the SS 6X MQ on my Kimbers has to be mounted hight in order to let the bolt handle pass....
