This video is a full instructional video of how to mount a scope to a Rossi Tuffy matched pair 410/22. I mounted a Bushnell scope to the 22 barrel using a Weaver rail and Modkin 1 inch high rings.
Rossi Matched Pair (Highly Recommended)
Weaver 92A Rail (Perfect Fit)
Modkin Rings (Works well with Weaver)
