Re: Leupold or Warne QD mounts??
Warne does make a detachable mount for the ruger 77/22 hornet or rimfire rifles. The model # for the Warne matte finish mounts is 1R7LM. Leupold does not, but from what i understand if you purchase a set of 'ruger to weaver style bases' you should be able to fit on a pair of leupold quick release weaver style rings onto the base but iam not 100% sure about this. Maybe someone who knows more can let us know.
B-Square, Ruger and also Weigand make the ruger to weaver style bases.
