The Unity Tactical FAST™ Optic Riser is designed to elevate compatible red dot optics to a 2.26" optical centerline, promoting a more natural, heads-up shooting position.

Faster Sight Picture
The FAST Riser raises compatible optics to Unity Tactical's signature 2.26-inch optical centerline, allowing shooters to acquire the reticle with less head movement.
This taller optic height encourages a more upright shooting position, reducing neck strain while making it easier to maintain awareness of your surroundings. It's especially beneficial when shooting on the move or transitioning rapidly between targets.
Optimized for Modern Equipment
The elevated height also provides additional clearance when using:
- Electronic hearing protection
- Communications headsets
- Ballistic helmets
- Night vision devices
- Gas masks
- Plate carriers and other protective equipment
By minimizing the need to lower your head into the stock, the FAST system helps maintain a more comfortable and efficient shooting position during extended use.
Broad Optic Compatibility
The FAST Riser is designed for block-style optics that utilize a standard lower 1/3 co-witness Picatinny mount, including popular models such as:
- EOTech EXPS Series
- Leupold LCO
- Vortex UH-1
- Other optics with a lower 1/3 co-witness mount
It can also accommodate certain absolute co-witness optics, although compatibility with Unity's FAST FTC Magnifier Mount may be limited.
Expandable Platform
The FAST Riser comes equipped with a secure rail-grabber clamp for direct Picatinny mounting.
For shooters who want integrated backup sight capability, Unity also offers an optional Flip-Up Offset Rear Iron Sight Module, compatible with many popular offset front sights from manufacturers such as Magpul, Midwest Industries, Knight's Armament, and others.
Premium Construction
Machined from 7075-T6 aluminum and finished with a Type III hard coat anodizing, the FAST Riser is built to withstand hard use while remaining lightweight.
Like all Unity Tactical products, it's engineered for professional-grade reliability without unnecessary bulk.
Our Thoughts
The Unity FAST system has become one of the most popular optic mounting solutions for good reason.
The 2.26" height takes a little time to get used to if you've only run traditional lower 1/3 mounts, but many shooters quickly discover how much more natural it feels—especially when wearing electronic ear protection or shooting from awkward positions. The improved posture and faster sight acquisition make it an excellent choice for defensive carbines, duty rifles, and modern training setups.
If you're looking to modernize your rifle without sacrificing durability, the Unity Tactical FAST Optic Riser is one of the best upgrades available.
