| 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. |
