The Scalarworks Low Drag Mount is the ultimate complement to the Trijicon RMR and provides an absolute co-witness
(center of iron sights is lined up with the center of the optic) and is the
lightest QD optic mount on the market without compromising any strength, weighing only 1.35 oz (38.4 grams) and
sports a streamlined profile free of protruding levers or knobs. The LDM410 features a tool-less precision telescoping clamping
system that firmly and securely mounts on to any 1913 rail (even those out of
spec without additional adjustments) by rotating the locking thumbwheel.
Low Drag Mount's precision guided telescoping clamp holds zero on every
re-installation, and under the heaviest recoil. Guaranteed. The LDM's
precision clamp features a pair of rounded shear lugs that provide a
high level of lateral impact resistance between the clamp and base.
