I tried to mount a 3-9x42 Vortex Diamondback on mine, Weaver low rings were just a hair too low, scope contacted the barrel. A Leupy Mark AR 3-9x40 fits perfectly in the same rings with just a little clearance to the barrel.

It's close enough that "low" rings from another brand might work fine for you.
