In addition to the Mausingfield action we showcased just before SHOT Show, American Rifle Company also displayed their M10 Scope Rings.
CNC machined in the USA from 7075 aluminum, these rings are available in 1″, 30mm, 34mm, 35mm, and 40mm (measured as top of rail to center of scope ring.). Their crowned rail interface tolerates out-of-spec Picatinny rails and maintains zero. Finally, with only one rail clamp screw and one scope clamp screw per ring, mounting is easy.
Additionally, ARC offers a QD-L Mount, available in 30, 34, and 35mm diameters, 35 and 40 mm heights, and inclinations ranging from 0 to 40 MOA.
