In Stock

The Scalarworks Low Drag Mount is the ultimate complement to the Trijicon MRO and provides a lower 1/3 co-witness (center of iron sights is in the lower 1/3 of the optic window). Without compromising an ounce of strength, the LDM/MRO is the lightest QD optic mount on the market, weighing only 1.5 oz (32.5 grams) and sports a streamlined profile free of protruding levers or knobs.

The 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.

The LDM/MRO has an intuitive quick detach attachment system that enables you to take it off in less than 3 seconds. Unlike conventional thumbscrews that rely on friction, the Low Drag Mount’s patent pending self-adjusting attachment mechanism has an internal ball detent that makes it completely recoil proof. Guaranteed.

Solid Build, Easy Attachment


The mount machining is impeccable. It looks straight and true. The mount is very light weight and mounted easily. I am very excited to finish this build and test its durability and return to zero (plan is to swap between this and a 1-6 Strike Eagle). Overall I am very impressed with it. It is amazing how the lighter things get, the more they cost. Rating 4 stars until I can get it out on some drills. Will update hopefully after it has seen some use.
