Our re-designed 30mm Sniper-Grade Scope Rings are not only more ergonomic, but are lighter as well. Each ring only weighs 8.5 ounces. Not bad for a ring manufactured from solid billet 4140 steel. Prior to being manganese phosphate treated, all components of the ring are carefully de-burred so as to eliminate any sharp edges. The square recoil cross lug will insure a positive engagement with the mounting rail. Four steel cap screws attach the top portion of the ring to the ring base. These rings are tall enough to accommodate a scope with a 56mm objective lens and Butler Creek lens covers on a Remington 700 BDL rifle.
