LaRue Tactical C.A.N SPR QD 1-Piece Cantilever Picatinny Scope Mount 34mm Rings Matte Black

From MidwayUSA

The LaRue Tactical C.A.N SPR QD Picatinny-Style Scope Mount is essentially the legacy LaRue Combat Proven QD mounts, with the slight change of no wrench needed to adjust the lever to the Picatinny rail. You adjust it by "clicking" the proprietary thumb nuts, much like clicking your scope turrets. It's very-fine click adjustment is real close to an infinite adjustment.Something interesting is you can "count the clicks" when switching optics between different uppers, allowing you to predictably maintain the torque on each rifle (and yes, you have to keep up with the scopes clicks, but you have to do that anyhow).
