The FAST™ Absolute Riser is engineered to securely elevate block-type red dot optics with an absolute co-witness height to the tactically advantageous 2.26 inch optical centerline.

Core Advantages and Compatibility

• Dedicated Absolute Height: Specifically optimized for optics that run at an absolute co-witness height, such as the EOTech® XPS® and Leupold® LCO®, providing a seamless transition to the 2.26 in platform.

Note: If you are running a lower 1/3 co-witness height optic, you need the FAST™ Optic Riser.

• Heads-Up Posture: The 2.26 in height promotes an ergonomically correct heads-up posture, facilitating faster/easier reticle acquisition and improving the user's ability to process the battlefield visually.
• Maximized Comfort: The heads-up posture helps users maintain a neutral spine position, enhancing comfort and sustainability while wearing heavy gear like helmets and plate carriers.
• Gear Clearance: Provides necessary clearance for operation while wearing essential gear such as night vision goggles and protective masks.

Construction and Modularity

• Premium Build: Constructed from robust 7075-T6 Aluminum and finished with a durable Type III Hardcoat Anodized coating (available in Black or FDE*).
• QD Ready: Comes standard with a rail clamp and is compatible with our ADM QD lever kit (sold separately) for quick detach functionality.
