American Rifle’s is a comprehensive scope mounting solution engineered to provide maximum clamping force without damaging the scope tube. Unique to the M3 patent pending design is a hinge on one side and an overlapping interface on the other used to secure the scope. The hinge minimizes the number of screws used to clamp the scope. The overlapping interface stems from the placement of those screws, which is critical to securing the scope without damaging it. The screws are tangent to the scope tube so that when tightened, the ring cap is pulled down over the scope tube without bending in a way that will damage the scope. The bottom part of the ring saddles the scope along 180 degrees of its circumference preventing the scope from moving laterally within the ring as the screws are tightened. American Rifle used finite element analysis (FEA) to engineer a scope ring that optimally distributes clamping forces over the scope tube. A force of 500 pounds* was applied at each screw location during the analysis to simulate the forces imparted by the screws. As depicted in the resulting stress plots below, the M3’s tangential scope clamp evenly distributes the clamp forces over the tube. As a result, no significant stress concentrations are present on the scope tube.
