i recently got a great deal on a 3-9x40 nikon prostaff at walmart. it was clearance priced at $74, regularly $180. i had decided i wanted to swap out this prostaff with my weaver kaspa currently on my axis ii 30-06. well, turns out it will not fit with the factory scope bases. whats your remedy for this? a DNZ 1 piece? will i have clearance issues in regards to the bolt? if so what height with this DNZ is recommended? thanks all!
