AD offset mount

• 45-degree offset layout: Positions a secondary sight at an angle for rapid transitions from a magnified optic to a close-range aiming solution without changing the rifle’s primary setup.
• Quick-detach lever system: The mount can be removed and reattached quickly, which helps when swapping optics between rifles or clearing space on the rail while keeping setup changes simple.
• Tool-free rail adjustment: American Defense’s lever design is made to fit in-spec and out-of-spec Picatinny rails without proprietary tools, making installation and tension adjustment more practical in the field.
• Aluminium construction: Keeps weight down while maintaining the rigidity needed for a stable optic interface on hard-use rifles and carbines.
• 15.00 mm base height: The compact profile helps keep the offset sight close to the rifle, reducing bulk and supporting a cleaner overall mounting arrangement.

About the AD Red Dot Mounts Series

American Defense AD Red Dot Mounts form a dedicated part of the company’s optic-mount lineup, covering compact red-dot applications across a wide range of firearm platforms. The series is built around practical mounting choices for popular optics such as Aimpoint Micro, Trijicon MRO, and other common red-dot footprints, with configurations tailored to different rifle setups and sighting heights. Within the range, users can choose from standard, TAC, or titanium QD lever variants depending on how they want to balance weight, handling, and locking style.

A defining feature of the series is the QD Auto Lock lever system, which is designed to fit both in-spec and out-of-spec Picatinny rails and can be adjusted without proprietary tools. In practice, that gives the AD Red Dot Mounts series broad compatibility and easier setup across different rifles and rail tolerances. The family also spans multiple height options, including low, co-witness, lower 1/3 co-witness, high, and night-vision heights, so the series suits everything from compact carbines to more specialized tactical optics arrangements. The overall design philosophy is straightforward: keep the mount light, secure, and adaptable to real-world firearm use.

About the AD offset mount

The American Defense AD offset mount is built for shooters who want a secondary sighting position alongside a primary optic. Its 45-degree offset configuration supports fast transitions to a red dot for close-range work, which is especially useful on rifles set up with magnified optics for hunting optics or tactical optics roles. Instead of removing the primary scope’s advantages at distance, the offset arrangement adds a faster option for nearer targets with only a slight rotation of the rifle.

The mount uses American Defense’s quick-detach lever system, giving it a practical advantage on rifles that may need frequent optic changes or rail reconfiguration. Because the lever system is designed to work with Picatinny rails and can be adjusted without proprietary tools, the mount is easier to fit across different rail dimensions while still maintaining a secure interface. That matters on working rifles where repeatable positioning and simple handling are more important than unnecessary complexity.

Its aluminium construction keeps the mount light enough for compact carbine and precision-rifle support roles, while the black finish gives it a subdued, equipment-focused appearance. The stated 15.00 mm height helps keep the assembly compact, which is useful when managing clearance around the main optic and preserving a streamlined rifle profile. For shooters using a Picatinny-based platform, this offset mount provides a clean way to add a secondary aiming solution without overcomplicating the rifle.
