AD SureFire M600B Scout light offset mount

• Offset light placement: Positions a SureFire Scout-pattern weapon light off the side of the rail, helping keep the beam clear of front sights, suppressors and support-hand grip space.
• QD Auto Lock lever: The patented quick-detach system lets the mount come on and off the rail quickly while maintaining strong clamping force on both in-spec and slightly out-of-spec Picatinny rails.
• Right-hand cantilever layout: The offset-cantilever configuration moves the light forward and outward, improving thumb access to tailcaps or remote-switch routing without crowding the top rail.
• 6061-T6 aluminum construction: A CNC-machined aluminum body keeps weight low while providing the rigidity needed for hard field use on rifles and carbines.
• Made in the USA: Domestic manufacture and a 10-year warranty make this mount a practical choice for users who want a durable long-term mounting solution for a fighting or utility rifle.

About the SureFire Scout Light Mount Series

American Defense SureFire Scout light mounts are built for shooters who want a secure, repeatable way to attach weapon lights to a Picatinny rail without adding unnecessary bulk. Within the company’s accessory lineup, this series covers dedicated mounting solutions for SureFire M600 and M300 Scout Light patterns and other lights that share the same footprint. The range includes standard, offset and cantilever variants, giving users different ways to position a light around handguards, front sights, lasers and sling hardware.

A defining feature across the series is the QD Auto Lock lever system, which is designed to clamp securely to a wide range of rail dimensions while remaining easy to remove without special tools. The design focus is practical rather than decorative: low weight, compact dimensions and fast handling on rifles set up for duty, defensive use or night shooting. Machined aluminum construction and hard-anodized finishes support regular field use, while the different mount geometries let the shooter place the light where activation is more natural and rail space is used more efficiently.

About the AD SureFire M600B Scout light offset mount

The AD SureFire M600B Scout light offset mount is intended for rifles and carbines that need a weapon light tucked close to the handguard but moved away from the top rail. Its offset, right-hand cantilever configuration helps place the light in a more accessible position for support-hand activation while also reducing interference with front sights, optics, lasers or other rail-mounted accessories. On a practical rifle setup, that means cleaner ergonomics and better use of limited mounting space.

The mount is designed around the SureFire M600/M300 Scout Light footprint, making it suitable for Scout-pattern light bodies in this format. Because the light sits offset from the rail, the beam can be pushed into a more useful position around the handguard, which is especially helpful on compact carbines where every slot matters. The cantilevered layout also helps move the light forward enough to reduce barrel shadow compared with a more central mounting position.

American Defense builds this mount from 6061-T6 aluminum, which keeps the assembly light while maintaining the stiffness needed for repeated removal and reinstallation. The company’s QD Auto Lock lever is a major part of the design: it allows fast attachment and removal, can be adjusted without proprietary tools, and is made to work with both in-spec and out-of-spec rail systems. For users who move accessories between rifles or need quick maintenance access, that combination of speed, secure lockup and compact offset geometry is the main advantage of this mount.
