the title pretty much says it all. i know that both rimfiretechnologies and EGW offer CZ 452 20 moa bases but as far as i can tell they only fit the 11mm dovetails that come on the 452 varmints and lux's. the american models use a 3/8" dovetail. does anyone know where i can pick up a 20 moa dovetail to picatinny base for an American model?
