I am looking for a 1 piece mount for my AI AX chassis. It needs to be 35mm and high enough to clear a 44mm USO objective on the AX chassis, ~1.25" minimum. I dont need the QD capability so throw levers are nice but not required. I see these mounts range from <$200 to $380 for the USO and $410 for the Spuhr. I have no problem dropping the coin but I am looking for experience and price justification.
