Any way you could turn one of the bases to move the slot? I've seen a few of the bases that don't center the slot over the screws and you can turn a base (usually the rear) such that it moves the slot closer to the front.
Is this a long or short action?
Might look at a one piece picatinny base... That way you can put rings wherever you need to on it. Weaver makes a picatinny base that is ~$35 and is a solid good base... They also make it in a 20MOA as well...http://swfa.com/Weaver-Tactical-Extended-Multi-Slot-Picatinny-Base-P46494.aspx - Straighthttp://swfa.com/Weaver-Tactical-Extended-Multi-Slot-Picatinny-Base-P46495.aspx - 20MOA
