Machined from hardened steel, this 30mm Picatinny QD Riflescope Mount from Riton Optics will hold your optic securely on any rifle with a Picatinny rail. Six screws secure the cap of each of the mount&';s two rings for a grip that can withstand the pressure of a day at the range. A tactical quick-detach mechanism allows you to respond quickly to changing circumstances, and the mount&';s built-in bubble level makes it clear right away whether your firearm is canted to either side or perfectly upright.
