Weaver Premium SPR 34MM Mount A specialized modern sporting rifle deserves high-quality accessories. The Weaver Premium Modern Sporting Rifle (MSR) Optics Mount is designed specifically for MSR rifles. The Premium MSR Optics mount lives up to its name starting with its construction. It's made of lightweight and supremely strong 7075-T6 aircraft-grade aluminum. The anodized Type III hardcoat black matte finish adds further protection and blends in seamlessly with the rifle. The sleek design sets optics at the ideal height with a forward cantilever for MSR rifles. The edges are slightly radiused to prevent snagging. The Weaver Premium MSR Optics Mount adds an extra layer of durability and performance but hardly any weight. - Premium MSR Mount 34mm
