Warne's Angleye is an adjustable, extreme long range scope ring system that allows the shooters to adjust between 0 to 90MOA; maximizing the amount of elevation travel their scope has to offer. It features a unique ability to zero a scope at long range using a minimal amount of the scope's internal adjustment, so that the optic can retain its maximum range of elevation travel. The rings are CNC machined from 7075/T6 aluminum with a Mil-Spec hardcoat anodized for durability and scratch resistance. They utilize Triple Torque caps for maximum scope tube contact and grip. The Angleye Rings are height adjustable with included riser inserts (3, 6 and 12.5mm additional height) and are Picatinny rail compatible.This model is compatible with your 30mm scope.
