Unity Tactical FAST
FAST Micro Prism Mount – 2.26″ for Primary Arms Micro Prism
For SLx and GLx Micro Prism scopes when you want to combine their fixed reticle logic with a high, more upright FAST sight line.

Does this fit your setup?


Fits well For Primary Arms SLx / GLx Micro Prism on M1913/Picatinny, especially on AR/carbine setups with deliberately high sight lines.


Fits less well For Aimpoint Micro, AEMS, ACRO, or RMR footprints and setups where a low sight line is more important.


What you practically get


2.26″ sight line The higher axis supports a more upright head position. This can be more comfortable with hearing protection, helmet, or plate carrier.


Prism-specific interface The mount is designed for Primary Arms Micro Prism scopes and avoids the false assumption that every micro optic uses the same footprint.


Stable rail attachment Two cross bolts clamp the mount onto M1913/Picatinny. An optional FAST QD lever can be added depending on the setup.


FAST system logic The height can be sensibly combined with suitable FAST magnifier solutions if optic, eye relief, and overall setup match.


Limits & avoiding bad purchases

The optic decides – not just the rail. This mount is not a universal red dot mount. Check the specific Primary Arms model before buying. A micro prism also has eye relief and diopter adjustment; therefore, its position must be precisely matched to your natural cheek weld. The higher sight line also increases mechanical offset at short distance.

Technical data with practical interpretation


Compatibility
Primary Arms SLx / GLx Micro Prism – key purchase point.


Axis height
approx. 2.26″ / 57.4 mm – for a deliberately high FAST line.


Mounting ba
sis
M1913 / Picatinny – fits only with a sufficiently clean rail surface.

Clamping
2 cross bolts – for a robust rail attachment.

QD option
Can be combined with optional FAST QD Lever.

Material / finish
7075-T6 aluminium, Type III Hardcoat according to existing product data.

Weight
approx. 85 g – additional weight remains manageable but is not zero.

Dimensions
approx. 5.3 × 3.3 × 3.8 cm.

Mounting & safe use
Clean mounting surfaces, tighten screws properly and according to manufacturer’s instructions, then check eye relief, diopter, and secure fit. After any change to the optic or mount, check point of impact. Train the increased close-range offset consciously.
Contents
Included: 1× Unity Tactical FAST Micro Prism Mount in chosen colour.
Not included, unless explicitly stated: optic, FAST QD Lever, magnifier, tools, and other accessories.

FAQ
Does the mount fit Aimpoint T2 or Holosun AEMS? No. Existing product data assign this version to Primary Arms SLx / GLx Micro Prism. Other FAST mounts are intended for other footprints.
Why is the 2.26″ height interesting? It can make your head position more upright, facilitating use with helmet, hearing protection, or plate carrier. The higher mechanical offset at short distance is part of it.
Do I need to re-zero after mounting? Yes. After changes to optic or mount, always check point of impact and re-confirm if necessary.
BLACK RAPTOR classification: A clear specialist solution for Primary Arms Micro Prism users. Strong if you consciously combine prism reticle and FAST ergonomics; unnecessary if your setup requires a low sight line or a different footprint.
