Looking for the lowest, Picatinny/Weaver, one piece scope base I can find. I don't want to re-do the rings already on the scope if I can help it. Currently have medium Weaver/tactical 6 screw. The scope. already torqued and leveled in the rings is a Kahles 2.2x9x42. I'd like really good cheek weld w/o using a comb pad or a Karsten. My budget is $100 I don't need 20 deg. MOA as my max range is 400 yards.
Any and all suggestions would be welcome

Thanks in advance
