AD Cantilever mount for Aimpoint Comp M2/M68

• Cantilever layout: pushes a 30 mm Aimpoint Comp M2/M68 pattern red dot forward on the rail, helping create a more natural head position and leaving more receiver space for backup sights or other accessories.
• QD Auto Lock lever: the patented quick-detach system lets the mount come off and go back on without proprietary tools, which is useful when switching optics or servicing the rifle in the field.
• Fits in-spec and out-of-spec Picatinny rails: the adjustable clamping system is designed to lock up securely across a wider range of rail tolerances, improving repeatability and reducing setup frustration.
• 6061-T6 aluminum construction: a lightweight but durable body keeps unnecessary weight off the rifle while still providing the rigidity needed for a stable red dot mounting platform.
• Lower 1/3 co-witness height: on AR-15 flat-top rifles with Mil-Spec iron sights, this height keeps the sight picture less crowded while still allowing irons to remain available if needed.

About the AD Red Dot Mounts Series

American Defense AD Red Dot Mounts are built as a broad family of quick-detach mounting solutions for popular red dot optics across different rifle and carbine setups. The series covers footprints and tube-style designs for sights such as Aimpoint Micro, Trijicon MRO, and Aimpoint CompM2/M68, with versions configured for AR-15 platforms as well as other firearm types. A key characteristic across the range is the company’s QD Auto Lock lever system, which is designed to clamp securely to both in-spec and out-of-spec Picatinny rails and can be adjusted without proprietary tools.

Within the series, American Defense offers several height options including low, co-witness, lower 1/3 co-witness, high, and night-vision heights, so the mount can be matched to the rifle’s stock geometry, iron-sight setup, and intended role. Lever choices also vary, with standard, TAC, and titanium configurations available in the wider family. In practical terms, the series is aimed at shooters who want a repeatable QD interface, straightforward installation, and a mount selection that can be tailored to everything from compact defensive carbines to rifles carrying larger tube-style red dots.

About the AD Cantilever mount for Aimpoint Comp M2/M68

The AD Cantilever mount for Aimpoint Comp M2/M68 is a dedicated 30 mm red dot sight mount built around the dimensions and use pattern of larger tube-style Aimpoint optics. Its cantilever design moves the optic forward relative to the rail, which is especially useful on AR-platform rifles where receiver space is limited and a more open shooting position is preferred. That forward offset helps balance eye position, keeps the charging area less obstructed, and leaves room for rear backup sights or magnifier setups depending on the rifle configuration.

This version uses American Defense’s patented QD Auto Lock lever system, giving the mount a fast on-off capability without relying on special tools. For practical use, that means the optic can be removed for transport, maintenance, or a rapid switch to irons while still using a clamping system intended for repeatable placement on Picatinny rails. The lever can also be adjusted to suit rail variation, which matters for shooters running different uppers or weapon platforms.

The mount body is made from aluminium, keeping weight under control while maintaining the stiffness needed for a stable optic interface. With a 23.50 mm mounting height and compatibility with Picatinny Rail platforms, this American Defense red dot mount suits carbines and rifles that need a detachable, repeatable solution for an Aimpoint Comp M2/M68 style optic. It is a practical choice for hunting optics or tactical optics setups where fast handling and dependable mounting matter more than unnecessary bulk.
