PA SLX 5x36MM Prism Gen 3- Review

Published on January 5, 2025
Duration: 32:27

This review of the Primary Arms SLX 5x36MM Prism Gen 3 optic highlights its ACSS reticle with ranging capabilities and dual illumination colors (red/green). While praised for its value and features like an adjustable diopter, the review notes limitations in glass clarity compared to higher-end optics, a smaller eyebox impacting rapid target acquisition, and a reticle design that can be suboptimal for close-quarters engagement. The optic is recommended as a capable entry-level magnified optic, particularly for those new to BDC reticles and magnification.

Quick Summary

The Primary Arms SLX 5x36MM Prism Gen 3 offers 5x magnification with an ACSS reticle featuring ranging and windage holds, plus dual red/green illumination. While its glass clarity and eyebox are not on par with premium optics like ACOGs, its affordability and feature set make it an excellent entry-level choice for learning BDC reticles and magnification.

Frequently Asked Questions

What are the key features of the Primary Arms SLX 5x36MM Prism Gen 3 optic?

The Primary Arms SLX 5x36MM Prism Gen 3 is a 5x magnification prism scope featuring an ACSS reticle with ranging capabilities, dual red and green illumination, 1/3 MOA turrets, and an adjustable diopter for reticle clarity. It also includes a removable 1913 rail for accessory mounting.

How does the ACSS reticle on the Primary Arms SLX 5x36MM Prism Gen 3 perform?

The ACSS reticle offers ranging for shoulder width and height, plus wind lead estimation. It includes a horseshoe for close distances with sprint and walking lead indicators. While functional, the horseshoe can obstruct close-range targets, and ranging accuracy degrades at 400+ yards in adverse conditions.

What are the main drawbacks of the Primary Arms SLX 5x36MM Prism Gen 3?

Key drawbacks include a smaller lateral eyebox compared to ACOGs, which can make rapid target acquisition difficult, and glass clarity that is warmer in tint and less refined than premium optics. The horseshoe reticle can also be obstructive at closer ranges.

Is the Primary Arms SLX 5x36MM Prism Gen 3 a good optic for beginners?

Yes, it's considered a good entry-level option for those new to magnified optics and BDC reticles. Its dual illumination and ACSS reticle provide valuable learning tools without the high cost of premium optics, serving as a solid stepping stone.
