The Talley Silver High Scope Rings 30mm for Kimber Models 17, 22, 82 and 84 are milled out of a lightweight alloy that rivals the strength of steel without the weight. It’s unique one-piece construction design removes the chance of a loose connection or an out of alignment interface between the rings and bases of traditional two-piece ring designs.
