Great rings,
January 8, 2007 N. Warner (Brighton, MI USA) - See all my reviews
My 10/22 has the "famous" receiver rise near the fore end; the Signature Zee rings are the only ones I didn't have to worry about damaging my scope with (scope $$ at least as much as the gun $$, right?).
With this system, a person can even purchase separate inserts that will directly counter effect significant receiver mis-alignment issues if that is needed. Gotta be the best way to preserve a scope while securely mounting it.
