Unity Tactical FAST MRO Mount – high 2.26" mount for Trijicon MRO

You use a Trijicon MRO or MRO HD on an AR platform and don’t want to crouch deep behind the optic.
The Unity Tactical FAST MRO Mount raises the optical axis to about 2.26 inches / 57.4 mm above the rail, supporting a more upright head position.

This is especially relevant for dynamic shooting, long body dimensions, protective mask, hearing protection, plate carrier, or night vision goggles. The mount is not just “higher,” but part of the FAST system logic: head more upright, faster target acquisition, accessories like magnifiers planned cleaner.

Important compatibility note:
This mount is designed for Trijicon MRO and Trijicon MRO HD.
It is not an Aimpoint Micro mount. Optics with Aimpoint Micro footprint do not automatically fit here.
Check before purchase: optic model, M1913/Picatinny rail, desired height, magnifier position, BUIS concept, and optional FAST QD lever.

What makes the Unity Tactical FAST MRO Mount practical:
✔ approx. 2.26" / 57.4 mm optical axis height for a more upright head position
✔ fits Trijicon MRO and MRO HD
✔ integrated, fully adjustable rear BUIS according to product data
✔ compatible with standard front backup sight
✔ standard 2-cross-bolt rail clamp for M1913/Picatinny
✔ compatible with optional FAST QD lever
✔ combinable with FAST FTC Magnifier Mounts
✔ 7075-T6 aluminum with Type III hardcoat finish

Why this product?

The benefit of the FAST MRO Mount is not just the height. What matters is how the raised optic line affects cheek weld, head position, and target acquisition.

With classic co-witness heights, you often have to crouch deeper into the stock. This can be uncomfortable with helmet, hearing protection, protective mask, or plate carrier. The FAST height allows a more upright posture and can bring the dot faster into your field of view – especially on AR15 and AR10 platforms.

2.26" optical axis: higher sight line for a more upright head position

MRO / MRO HD fit: specifically designed for Trijicon MRO optics

Integrated BUIS: rear backup iron sight already integrated in the mount

Magnifier logic: designed for use with FAST FTC Magnifier Mounts

QD upgradeable: standard clamp can be supplemented with FAST QD lever

7075-T6 aluminum: stable base for a permanently stressed optic mount

Instructor tip: Higher optic line changes your close range
At 2.26", the sight line sits significantly higher than with Absolute or Lower-1/3 co-witness. At short distances, the mechanical offset increases.
Train deliberate hold points at 5, 10, and 15 m. This is crucial especially for small targets or precise shots at close range.

Our assessment

The Unity Tactical FAST MRO Mount makes sense if you want to not only mount your MRO but integrate it into a modern AR/carbine setup. It plays to its strengths when head position, gear, and accessories need to fit together.

For pure benchrest, classic hunting, or simple range setups, the FAST height is not automatically better. Those who want to work very low behind the firearm or prefer a classic co-witness image e
rwartet, you should consciously check the height.

Useful for:

AR15 and AR10 platforms with Trijicon MRO or MRO HD
dynamic shooting and carbine training
use with hearing protection, helmet, protective mask, or plate carrier
shooters with larger body size or more upright shooting position
setups with FAST FTC Magnifier Mount
users who want to use an integrated Rear BUIS

Less useful for:

optics without Trijicon MRO footprint
classic low-mount or co-witness setups
hunting rifles with low stock line
users who do not want to train the increased close-range offset
setups where minimal height is more important than head position

FAST 2.26" or Lower 1/3 Co-Witness?
✔ FAST 2.26": more upright head position, better with gear, NVG, and magnifier setups
✔ Lower 1/3: lower, familiar, often easier for classic range setups
FAST is not an end in itself. The height must fit your weapon, your shooting position, and your training profile.

Co-Witness clearly explained

Co-Witness describes how the red dot and mechanical sights relate to each other.

Absolute Co-Witness: red dot and mechanical sights are roughly on the same line

Lower 1/3 Co-Witness: the mechanical sight sits in the lower third of the red dot’s field of view

FAST 2.26": significantly higher optic line; classic BUIS no longer lie directly in the normal red dot sight picture

The FAST MRO Mount solves this with an integrated Rear BUIS. This keeps a backup sighting option possible without having to place a normal rear sight directly behind the mount.

Practical tip: don’t just mount BUIS – really check it
A backup iron sight only helps if you have zeroed and understood it.
Check the integrated Rear BUIS together with your front sight. Also test whether your optic, magnifier, and handling do not hinder access.

Use scenarios

AR / Carbine: raised MRO position for faster target acquisition and more upright posture

Dynamic training: less deep rolling behind the optic during quick position changes

NVG / night vision: higher sight line can facilitate use with night vision goggles

Hearing protection / helmet / protective mask: less conflict between head position and gear

Magnifier setup: combination with FAST FTC Magnifier Mounts possible

Tall shooters: more upright shooting position can be significantly more comfortable

Features & construction clearly explained

Trijicon MRO / MRO HD interface: specifically built for these optics, not for Aimpoint Micro

2.26" optical axis height: raises the point above the rail and supports heads-up shooting

M1913/Picatinny: mounting base for AR15, AR10, and compatible rail systems

Integrated Rear BUIS: backup sight at the rear, fully adjustable according to product data

Standard front sight compatible: can form a classic backup sight line with a matching front sight

2-cross-bolt rail clamp: standard clamping for secure mounting on the rail

FAST QD lever compatible: quick-release lever can be retrofitted separately

7075-T6 aluminum: high strength with low weight

Type III hardcoat: durable surface resistant to abrasion and wear

Important mounting note:
After mounting or changing the optic mount, the point of impact must be checked.
Use correct torque, suitable screws, and appropriate thread locker according to manufacturer specifications. Also check the mechanical offset at short distances.

Variants & selection

Black: neutral for black AR and optic setups

FDE / Tan: suitable for FDE, Coyote, or two-tone setups

The decisive factor is not the color but the correct optic: This mount is intended for Trijicon MRO and MRO HD.

FAQ

Does the Unity Tactical FAST MRO Mount fit Aimpoint Micro optics?
No. This mount is designed for Trijicon MRO and MRO HD. Aimpoint Micro, SIG Romeo4 or similar Micro-Footprints require suitable Micro-Mounts.

What does 2.26" optical axis height mean?
The center of the optic sits approx. 2.26 inches or 57.4 mm above the rail. This allows a more upright head position but increases mechanical offset at short distances.

Does the mount have an integrated BUIS?
Yes. According to product data, the FAST MRO Mount features an integrated, fully adjustable Rear Backup Iron Sight. For complete emergency sighting, you need a suitable Front Sight.

Can I use a QD lever?
Yes. The mount comes with a standard clamp and is compatible with the optional FAST QD Lever. The QD lever is sold separately.

Do I need to re-zero after mounting?
Yes. After any change to the optic or mount, point of impact must be checked and re-zeroed if necessary.

For whom is the FAST height not ideal?
For users who want a low classic Co-Witness height or do not want to train the higher close-range offset. The height must fit the cheek weld and use profile.

Conclusion: The Unity Tactical FAST MRO Mount is a specialized, high mount for Trijicon MRO and MRO HD. It is especially useful for AR/Carbine setups where upright head position, magnifier use, gear on the head, and clear system logic are more important than the lowest possible optic line.
