The Primary Arms SLx 1X MicroPrismT is an unmagnified prism scope with a glass-etched T-Dot reticle under red RDB illumination, built on the H1/T1 micro-dot footprint and supplied with a 2.26in mount.
The reticle is cut into the glass, not projected by an LED, so it stays sharp for eyes that see a red dot as a smear — and it is still there when the battery is flat.
Power is a single CR2032 lithium coin cell, and Primary Arms describes the illumination as partial, meaning the reticle is a dark etched pattern with the illuminated element lit on top. It is night-vision compatible, and the finish is black. Windage and elevation move in 1 MOA clicks with 120 MOA of travel available on each axis.
This is the one MicroPrism reticle with no ranging marks in it. Where the ACSS reticles give you holdovers, leads and stadia to read, the T-Dot gives a clean aiming point and a post below it, which is faster if you were never going to use the rest. Bear in mind it is a prism scope with a fixed dioptre focus, so it wants setting up once for your eye.
Why shooters choose the SLx 1X MicroPrismT
-
Reticle — T-Dot etched into the glass, so it works with the illumination off
-
Astigmatism — an etched pattern viewed through the optic's own focusing system, not a projected LED
-
Illumination — red RDB, night-vision compatible, from one CR2032 cell
-
Adjustment — 1 MOA per click with 120 MOA of windage and elevation travel
-
Footprint — H1/T1 micro-dot pattern, with a 2.26in mount supplied
-
Magnification — true 1x, so both eyes stay open
What the SLx 1X MicroPrismT fits
The H1/T1 footprint means it accepts the wide range of mounts made for micro red dots, and the 2.26in mount in the box covers a flat-top rifle. For a reticle with ranging and holdover references, the same optic is offered with the red ACSS Cyclops Gen II or the green ACSS Cyclops Gen II, and the wider category is in prism scopes.
