A compact, general-purpose prism optic with a reticle etched into glass for reliability, best suited to shooters who want simplicity over the caliber-specific ballistic calibration found on the Gemini version, and with the same caveat: bring your own low mount if you need one.

This version of the Primary Arms SLX 1X MicroPrism swaps in the ACSS Cyclops Gen II reticle, a bold single center aiming point with built-in ranging, rather than the 9mm-specific Gemini reticle used on the sibling model.
Where the Gemini variant targets 9mm carbine shooters specifically, the Cyclops Gen II reticle is a simpler, high-contrast dot-style aiming point meant to work across a broader range of calibers and use cases. The same mount discrepancy applies here too: the box, manual and listing all reference a low mount that does not actually ship with the unit.
- ACSS Cyclops Gen II center aiming reticle
- 76.5 ft field of view at 100 yards
- 15.6mm exit pupil, 3.6 inch eye relief
- H1/T1 footprint, IP67 rated
Who it's for
A fit for shooters who want a fast, uncomplicated aiming reference rather than a caliber-specific BDC ladder, on a compact optic that still works with the reticle etched into glass if the battery dies.
Pros and cons
- Etched glass reticle stays usable with no battery
- Wide 15.6mm exit pupil and 76.5 ft field of view
- Compact at 2.48 inches and 5.5 oz with battery
- AutoLive motion sensing conserves battery life
- Ships with only the high mount despite documentation stating otherwise
- Cyclops Gen II reticle has no caliber-specific BDC ladder
Performance notes
At 2.48 inches long and 5.5 oz with battery, the optic adds minimal weight to a host firearm, and a 76.5 foot field of view at 100 yards with 3.6 inch eye relief gives a forgiving sight picture for fast target pickup. The 15.6mm exit pupil is notably wide for a prism optic, which helps eye alignment speed when shouldering the weapon under time pressure.
