Weaver 1" Grand Slam Top Mount Scope Rings High / Silver - Weaver has re-designed the classic Grand Slam Rings with 4 screws instead of 2 for more positive scope holding power. Grand Slam Rings are constructed of solid steel which yields amazing strength and scope retention.  Scope returns to zero upon reinstallation.
 
CHOOSING RINGS: Ring height is determined by measuring the outside objective (bell) diameter on your scope.
