AD riser mount R2 for EOTech

• QD Auto Lock lever: The quick-detach system lets the riser come off and go back on the rail without tools, which is useful when swapping optics or reconfiguring a rifle while keeping a consistent mounting position.
• Built for EOTech EXPS optics: This R2 version is made for QD EOTech EXPS models, giving the correct interface for optics that already use EOTech’s built-in quick-detach base.
• 0.40" height increase: The riser lifts the optic to a 2.1" center height, creating a taller sight line that can feel more natural on modern carbine setups and can help with faster head-up shooting positions.
• Adjustable rail fit: The mount is designed to fit in-spec and out-of-spec Picatinny rails, so it can clamp securely across a wide range of rifles and rail systems without proprietary tools.
• 6061-T6 aluminum construction: The aluminum body keeps weight low while providing the rigidity needed for a repeatable optic mount that stands up to regular field use.

About the AD Red Dot Mounts Series

American Defense AD Red Dot Mounts are part of the company’s broader family of optic mounting solutions for carbines and rifles. Within the lineup, the series focuses on compact sighting systems and related platforms, including mounts for Aimpoint Micro, Trijicon MRO, Aimpoint CompM2/M68, and other red-dot patterns. A defining feature across many models is the company’s patented 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.

The series is built around practical configuration choices rather than one universal height. Depending on the application, mounts are offered in low, co-witness, lower 1/3 co-witness, high, and night-vision heights, with lever options that include standard, TAC, and titanium versions. That makes the range relevant for everything from straightforward AR-15 setups to more specialized platforms where head position, backup sight clearance, or accessory alignment matter. The design approach stays consistent: lightweight aluminum construction, repeatable quick-detach handling, and mounting geometry tailored to the optic it is meant to carry.

About the AD riser mount R2 for EOTech

The AD riser mount R2 for EOTech is a dedicated red dot sight riser for shooters using QD EOTech EXPS holographic sights. Unlike a generic Picatinny spacer, this model is built around the dimensions and mounting style of the EXPS family, so it solves a specific setup problem: raising the optic without changing to a different sight. American Defense states that the ETECH-R2 raises the optic 0.40" and provides a 2.1" center height, a configuration that supports a more upright shooting posture on modern carbines and can be especially useful when running gear that makes a lower cheek weld less comfortable.

The mount uses the company’s QD Auto Lock lever system, which is one of the main reasons to choose it over a fixed riser. It allows fast removal and reinstallation, and it can be adjusted with a finger or a flat blade screwdriver rather than a proprietary wrench. In practice, that makes the mount easier to tune to different rail tolerances and easier to service in the field. The lever can also be configured to lock to the front or rear, which helps when working around charging handles, magnifiers, or other rail-mounted accessories.

Construction is equally purpose-driven. The riser is precision CNC machined from 6061-T6 aluminum and finished with hard coat type 3 Mil-Spec anodize, giving it the low weight expected from a carbine optic mount while maintaining the surface hardness needed for repeated attachment and removal. For users who want an EOTech EXPS mounted higher on a Picatinny rifle without giving up quick-detach convenience, this model is a focused and mechanically simple solution.

About American Defense

American Defense MFG, LLC is based in New Berlin, Wisconsin and is known for quick-detach mounting solutions for optics and firearm accessories across a wide range of firearm platforms. The company states that its mounts and rifles are designed and built in the United States, reflecting a product focus on domestic manufacturing and platform-specific engineering. A key part of its reputation in the optics-mount segment is the patented QD Auto Lock lever system, used across many of its mounts to provide repeatable attachment on Picatinny rails without proprietary adjustment tools.

Beyond red-dot mounts, American Defense’s catalog includes scope, magnifier, thermal and night-vision, bipod, tripod, light, and laser mounts, along with fully ambidextrous AR-15 and AR-10 pattern rifles. That breadth matters here because it shows the company’s emphasis on mounting geometry, interface compatibility, and practical handling rather than one single product niche.
