Check intothe Tactical Precision Systems TSR-W low rings. http://www.tacticalprecision.com/TSR%20W-Series.htm
They are very tough, cost around $75 , cheaper if you can get the discount at Brownells, they look good and work great, should get your scope low enough. I have a set of these on a 20-MOA Farrell baseusing a Sightron 4x16x42AO, and a set of Farrell standard rings on a 0-MOA Farrell base using a 3x9x40 Leupold Tactical. In one of your other posts I think you refered to there being a 3/8" gap between scope and barrel, I just don't see that as excessive, maybe it's just me. I want a good solid strong mount and I do not care so much about how much gap there is between the scope and barrel. As far as the cheek weld, most of the shooters I know have had to go to an adjustable cheekpiece or get some sort of stock pack and put a piece of foam in there to get to the right height.
