Trijicon RMR Footprint Mount: The Definitive Secondary Optic Mount for ACOG 4x32 LED Integration 

• The Trijicon RM66 Footprint Mount is a field-proven hardware bridge designed specifically for the front mounting bosses of the ACOG 4x32 LED scope. This precision piggyback mount allows operators to securely attach a micro red dot sight for instantaneous CQB transitions and close-quarters targeting.
• Keeps Your Rifle Light at Only 0.6 Ounces: Machined from high-strength aircraft-grade aluminum, this plate secures your secondary optic while maintaining an exceptionally high strength-to-weight ratio. When combined with a standard micro red dot, the entire top-mounted setup adds less than 2 ounces to your rifle.
• Clears Night Vision Goggles: The plate bolts directly to the extreme front of the TA02 ACOG, positioning the red dot far away from bulky head-mounted night vision tubes to ensure unobstructed passive aiming and a proper optical centerline.
• Survives Extreme Thermal Shocks from -20°F to 140°F: This mount screws directly into the ACOG's forged bosses to match the legendary "Science of Brilliant" testing standards of the primary scope. It establishes a monolithic base that maintains your zero through severe temperature changes, heavy weapon recoil, and violent physical drops.
• Secures 4 Unique Optic Profiles: The top plate features precise threads and geometry built specifically for the Trijicon RMR, SRO, RCR, and RMR HD reflex sights. You can bolt these micro optics straight onto the hardware bridge, eliminating the critical failure points created by stacking weak aftermarket adapter plates.

Trijicon RMR Footprint Mount Features & Specifications

The Trijicon RMR Footprint Mount (RM66) is a combat-proven mounting solution engineered for the ACOG 4x32 LED optic. Unlike traditional rear-mounted adapter plates, its forward design positions the micro red dot farther along the optic body, eliminating potential interference with helmet-mounted Night Vision Goggles (NVGs). This configuration also provides a less obstructed field of view, helping users maintain greater peripheral awareness and acquire targets more quickly in low-light and dynamic environments.

Key Features

• Front-Boss Integration: Attaches directly to the forward bosses of the TA02 ACOG, positioning the red dot away from the ocular lens to easily clear bulky night vision equipment for effortless passive aiming.
• Heads-Up Posture Dynamics: Creates a deliberate height-over-bore that encourages a modern "chin weld" stance, reducing cervical neck strain and naturally opening your respiratory airway during prolonged use.
• Direct-Fit Ecosystem: Provides a native, structural base for the standard RMR footprint, eliminating the need to stack fragile, aftermarket adapter plates that can fail under recoil.
• Enhanced Situational Awareness: Pushing the red dot housing further forward on the visual plane makes it appear smaller to the eye, preventing the secondary optic from becoming a dangerous blind spot during rapid target acquisition.

Trijicon RMR Footprint Mount FAQs

What is the Trijicon RMR Footprint Mount?

The Trijicon RMR Footprint Mount (RM66) is a precision-machined, lightweight hardware bridge. It functions as a piggyback mount, allowing operators to secure a secondary micro red dot sight directly to the front bosses of an ACOG TA02 scope for rapid CQB transitions.

Will this fit straight on my rifle's rail?

No. This mount interfaces specifically with the forward bosses of the Trijicon ACOG 4x32 LED scope. It is not designed to mount directly to MIL-STD-1913 Picatinny rails.

What red dot sights work with this plate?

This adapter plate is precisely machined to accommodate the standard Trijicon RMR footprint. It natively supports the Trijicon RMR, SRO, RCR, and RMR HD reflex sights without requiring additional, stacked aftermarket adapter plates.

Does this kit come with everything I need?

Yes. The kit includes the RM66 mounting plate, four specialized screws for securing the mount to the ACOG's bosses, and two optic screws for mounting your selected red dot sight.

How do I know if I need this over other RMR mounts?

If you operate a TA02 ACOG and require a secondary optic with a raised optical centerline for passive NVG aiming or rapid close-quarters engagements, this forward-positioned mount is the required hardware.
