Unity Tactical FAST™ Red Dot Riser – Raises Lower-1/3 Mounts to 2.26" Optical Height – Direct-to-Picatinny – Anodized Black (FST-ORB / FSTORB) – UPC 810007880051

Get the head-up posture modern carbines were built around. The Unity Tactical FAST™ Red Dot Riser lifts a lower-1/3 co-witness red-dot or holographic mount to a true 2.26-inch optical height, delivering faster sight acquisition, easier passive aiming behind NODs, and a more natural, shoulders-up stance when you’re wearing armor or running a gas mask. Machined for duty use and finished in hard anodized black, Model FST-ORB (FSTORB), UPC 810007880051 bolts directly to Picatinny rails and plays perfectly with a wide array of optics that already sit at lower-1/3 height.

Who it’s for: Duty carbines, night-vision users, competitive shooters, and anyone who wants a consistent, heads-up sight picture with less neck strain and faster target transitions.

Why the FAST™ Riser Changes the Game

• True heads-up shooting (2.26" centerline): Clears chest rigs and plate carriers, promotes airway alignment, and reduces neck flex so you can stay on the gun longer with less fatigue.

• Optimized for NVG/passive aiming: Extra height helps you passively aim under night-vision without breaking cheek weld or resorting to active illuminators.

• Instant upgrade for lower-1/3 mounts: Drop the riser under your existing lower-1/3 co-witness optic to achieve the ideal 2.26" height—no need to replace your favorite mount.

• Direct Picatinny interface: Secure, repeatable 1913 attachment anchors the riser to your rail—no adapters or proprietary systems.

• Hard-use build: Precision-machined body with a tough anodized finish for corrosion, abrasion, and weather resistance in real-world conditions.

• Clean cable / laser deconfliction: Extra vertical space helps route tape switch leads and maintain line-of-sight around PEQ/MAWL-style devices.

Key Identifiers

• Brand: Unity Tactical

• Product: FAST™ Red Dot Riser

• Function: Elevates lower-1/3 red-dot/holographic mounts to 2.26" optical height

• Mounting: Direct to Picatinny (1913)

• Finish/Color: Black, hard-anodized

• Model #: FST-ORB / FSTORB

• UPC: 810007880051

Feature Highlights

• Precision elevation geometry: Consistent POA/POI through the full rail length; engineered flatness for tight parallelism with receiver rails.

• Low-profile footprint: Adds height without bulky mass or snag-prone edges; maintains a tidy rail layout for BUIS, lasers, and lights.

• Torque-friendly hardware: Quality fasteners and clamping surface area provide reliable retention under recoil and temperature swings.

• Optic-agnostic design: Works with many optics that mount on Picatinny at lower-1/3—simply place your existing mount on the riser to reach 2.26".

• Armorer-friendly: Install or remove with basic tools; return the rifle to standard height in minutes as mission requirements change.

Compatibility note: Designed to elevate lower-1/3 Picatinny-based red-dot/holographic mounts. Always verify your optic’s base height and rail clearance before installation.

Performance You’ll Notice

• Faster dot pickup: The heads-up posture places the window naturally in your line of sight during mount, improving first-shot cadence.

• Better ergonomics in armor: High-ride height clears front plate bulk and chest straps, helping you square up behind the gun without turtling your neck.

• Cleaner passive aiming: NVG tubes line up more cleanly behind the optic, reducing shadowing and nod-to-optic interference.

• Smoother transitions: Upright posture keeps your peripheral vision open for rapid target-to-target work in CQB and dynamic stages.

Ideal Setups & Use Cases

• LE/MIL duty carbines: Optimize posture with plate carriers, radios, and helmets in the stack or on patrol.

• Night-vision training: Maximize passive aiming performance during low-light blocks without changing your core grip.

• 2-gun/3-gun & USPSA PCC: Speed up presentations and transitions; reduce neck strain over long match days.

• Home defense & training rifles: Keep the sight naturally aligned in everyday clothing or layered winter gear.

Quick Installation (Overview)

1. Unload & clear the firearm; verify safe.

2. Place the riser on a Picatinny (1913) rail section; seat fully.

3. Torque to spec per Unity’s guidance for the cross-bolts.

4. Mount your optic (already lower-1/3) to the riser; torque per the optic/mount manufacturer.

5. Confirm zero: Because mechanical height changed, re-verify zero before use.

Follow manufacturer torque values. If unsure, consult a qualified armorer.

Best Practices & Care

• Re-zero after install: Height change affects trajectory at close distances; confirm 25/50/100 as needed.

• Check fasteners: Verify torque after the first range session and periodically thereafter.

• Mind thermal zones: Leave appropriate rail gap from hot suppressors or gas blocks to minimize heat soak.
