Scalarworks makes some pretty nice (and light weight) optics mounts. Their minimalist styled Low Drag Mount Aimpoint Micro mount weights only 1.33oz and looks pretty sweet. They also make a really good optics mount for the Benelli M4 shotguns that we did a write up on last year.
Their newest optics mount is one of a kind according to Scalarworks. Their new Low Drag Mount for the Aimpoint CompM4 optic is the lightest quick detach mount for the CompM4 according to Scalarworks. It weights in at just 1.49 oz, that’s including the sight screws. The next lightest mount on the market is actually Aimpoint’s own QRP2 Mount which weights in at 3.53 oz. The Scalarworks Low Drag Mount has a monolithic base that’s made out of high-strength 7075-T6 aluminum that features Scalarworks proprietary recoil-proof notched thumbscrew with a ball detent. Scalarworks claims it takes only 3 seconds to detach their mount from your rifle. The Low Drag Mount works with MIL-STD-1913 Picatinny rails and Scalarworks guarantees that you’ll retain zero if you remove then reinstall the mount.
The Low Drag Mount is available in both an absolute or lower-third co-witness. They’re made in the USA and retail for $149 and include a lifetime warranty. Check them out at scalarworks.com for more info.
