Precision machined from one solid piece of 7075-T6 aircraft grade aluminum, the BackCountry Scope Bases deliver a rock-solid interface between your optic and firearm, and are every bit as rugged and reliable as Leupold's premium optics. The BackCountry Scope Bases are available in a massive selection of options for specific rifles, and many feature an inclination to extend the elevation adjustment range on the mounted optic.Features:Precision machined from one solid piece of 7075-T6 aircraft grade aluminumLightweight & DurableAvailable in a massive selection of options for specific riflesSpecifications:Inclination: 20 MOAItem Condition: NewProduct Type: Scope Mounts
