these little rings are a great match with the Weaver Scout Scope. I have them both on a Weigand rail on my Mini-30, and are holding zero after multiple magazines. use a bit of loctite and you are good to go!
Pros: vice like grip! half as many screws.
Cons: can scratch your scope if you aren't careful.
