Just received my 457 MTR, and have a Nikon Black x1000 6-24x50sf matte il x-moa due any day. Normally I would just order a set of CZ 11mm, 30mm high rings, but there doesn't seem to be any available in Canada ! I have looked at Talley, Warne, etc. all in 11mm & 30. but few are available. I am starting to think of a rail, and get away from 11mm rings. What rail-ring combinations are people using on their MTR's ?
