Advanced 1x Prism Optic with True Daylight Bright® Illumination

The Primary Arms GLx 1x MicroPrism™ brings premium optical performance to the close-quarters prism optic category. Designed for fast target acquisition, durability, and adaptability across platforms, the GLx 1x delivers the rugged reliability of a prism scope with the lightweight usability of a red dot sight.

Part of the advanced GLx® optics line, this MicroPrism introduces upgraded glass clarity, push-button controls, AutoLive® technology, and an enhanced Daylight Bright® reticle system — all in a compact 2.6” footprint.

Superior Glass Clarity & Edge-to-Edge Resolution

With its wider objective lens and updated internal optical design, the GLx 1x MicroPrism provides:

  • Exceptional edge-to-edge clarity
  • Enhanced light transmission
  • Fully multi-coated lens
  • Precise ½ MOA adjustments

The result is a crisp sight picture with generous field of view, optimized for close quarters while maintaining precision at extended practical distances.

Near Unlimited Eye Relief for Any Platform

Unlike traditional prism scopes, the GLx 1x MicroPrism features near unlimited eye relief, allowing consistent performance across:

  • AR-15 platforms
  • AK variants
  • PCC builds
  • Night vision setups

This forgiving eye box improves speed, comfort, and consistency in dynamic shooting positions.

Red ACSS Cyclops Reticle – Fast & Precise

The Red ACSS Cyclops reticle is engineered for intuitive shooting.

  • Large outer horseshoe for rapid acquisition
  • Infinitely precise center chevron
  • Integrated auto-ranging ladder for quick distance estimation

Because the reticle is etched, it works even without illumination — making it an excellent solution for shooters with astigmatism.

A built-in diopter adjustment allows for precision reticle clarity tailored to your eyesight.

Daylight Bright® Illumination with AutoLive® Technology

Using advanced LED technology, the GLx 1x MicroPrism offers:

  • 13 illumination settings
  • 3 dedicated Night Vision settings (Low, Medium, Flood)
  • True Daylight Bright® maximum setting
  • AutoLive® motion-sensing on/off system
  • Up to 14,925 hours battery life (setting 5)
  • (1) CR2032 battery included

AutoLive® ensures the optic powers on when moved and enters low-power sleep mode when idle — preserving battery life for dependable “always ready” storage.

Slimmer Profile. Lightweight Build.

  • Length: 2.6”
  • Weight: 9.1 oz
  • Slimmer than the SLx 1x
  • Compact footprint

This makes it ideal for minimalist builds, lightweight carbines, and streamlined defensive setups.

8 Mounting Height Options Included

The included ruggedized mounting system features an industry-standard mini-prism footprint and offers 8 mounting height configurations, ranging from:

  • 1” centerline (AKs & low-comb stocks)
  • Over 2” centerline (night vision & heads-up shooting)

No matter your platform or shooting style, the GLx 1x MicroPrism adapts easily.

Built for Real-World Durability

  • IP67 waterproof
  • Nitrogen purged for fog resistance
  • Dust proof
