AD mount for Aimpoint Comp M4

• Quick-detach lever system: American Defense’s QD Auto Lock lever lets the mount come off and go back on quickly while maintaining a secure hold on the rail, which is useful when swapping optics between rifles or removing the sight for transport and maintenance.
• Fits Aimpoint CompM4 optics: This mount is built specifically for the Aimpoint CompM4 interface, giving the optic a stable, properly matched base instead of relying on generic adapters.
• Low 13.00 mm height: The low-profile configuration keeps the optic close to the rail, which suits platforms and setups where a minimal sight line is preferred and extra height is unnecessary.
• 6061-T6 aluminum construction: The aluminum body keeps weight down without giving up the rigidity needed for a dependable optic mount on hard-use rifles.
• Made in the USA: Domestic manufacturing supports consistent machining, finish quality, and parts compatibility across American Defense’s quick-detach mounting system.

About the AD Red Dot Mounts Series

American Defense AD Red Dot Mounts are the company’s dedicated family of quick-detach mounts for compact and full-size red dot sights used on modern sporting, duty, and tactical rifles. A defining feature across the series is the patented QD Auto Lock system, which is designed to fit both in-spec and out-of-spec Picatinny rails and can be adjusted without proprietary tools. That matters in practice because it makes the mounts easier to set up correctly across different rifles and rail tolerances.

Within the series, multiple height options are offered to match different shooting positions and sighting setups, including low, co-witness, lower 1/3 co-witness, high, and night-vision heights. The range also spans mounts for optics such as Aimpoint Micro, Trijicon MRO, and Aimpoint CompM2/M68 and CompM4-pattern sights, with lever options that vary by model. The overall design philosophy is straightforward: keep the mount strong, repeatable, and easy to remove, while giving the shooter a height and lever configuration that suits the rifle and optic combination rather than forcing a one-size-fits-all solution.

About the AD mount for Aimpoint Comp M4

The AD mount for Aimpoint Comp M4 is a dedicated quick-detach red dot mount built for shooters who want a secure interface for the Aimpoint CompM4 on a Picatinny rail. Its main advantage is not complexity but fit: because it is designed around this optic pattern, it provides a stable base that supports consistent alignment and dependable retention under repeated handling. For users running a full-size duty-style red dot, that model-specific fit is more important than a generic mount that only approximates the footprint.

This version uses a 13.00 mm height, giving it a low mounting position that keeps the optic close to the bore line. That makes it especially suitable for rifles or chassis systems where a raised AR-style sight height is not required. The mount is made from 6061-T6 aluminum, so it remains light enough not to add unnecessary bulk while still offering the stiffness expected from a hard-use optic base. American Defense’s QD Auto Lock lever is the key functional feature: it allows fast removal and reinstallation, adjusts without special tools, and is intended to work across varying rail tolerances. In practical use, that means easier optic changes, simpler transport, and a mount that can be tuned to the rail rather than forced onto it. For a CompM4 setup on a rifle with a Picatinny top rail, this mount focuses on secure attachment, repeatable positioning, and straightforward field handling.
