This review of the Primary Arms SLX RS10 optic highlights its initial promise with a narrower RMR-style footprint for better handgun integration and an elevated sight picture. However, significant drawbacks emerge, including a non-standard Doctor footprint, a misleadingly tall window, a poor red dot refresh rate causing trailing, and a perceived lack of brightness compared to competitors. Despite a competitive price point, these issues lead to a recommendation for a Gen 2 model.

Quick Summary

The Primary Arms SLX RS10 optic presents a narrower RMR-style footprint for handgun integration and an elevated sight picture. It features an improved battery tray with a CR2032 battery and low distortion. However, its Doctor footprint is outdated, the tall window is deceptive, and a poor refresh rate causes noticeable dot trailing, impacting usability.

Frequently Asked Questions

What are the main advantages of the Primary Arms SLX RS10 optic's design?

The SLX RS10 features a narrower RMR-style footprint for better handgun integration and an elevated sight picture. It also boasts an improved battery tray using a CR2032 battery and a full-size screw, along with low tint and distortion levels.

What are the significant drawbacks of the Primary Arms SLX RS10?

Key issues include its outdated Doctor footprint, a misleadingly tall window where the dot cannot be seen, and a poor red dot refresh rate causing noticeable trailing during recoil, making target acquisition more difficult.

How does the Primary Arms SLX RS10 compare to an RMR?

While the RS10 offers a narrower footprint and elevated sight picture, the RMR has a functionally larger window because its dot can extend beyond the optic's physical edges. The RMR is also not limited by a Doctor footprint or a poor refresh rate.

Is the Primary Arms SLX RS10 a good value for its price?

At $200, the SLX RS10 is competitively priced. However, its significant design flaws, particularly the Doctor footprint and refresh rate issues, detract from its value, leading the reviewer to suggest waiting for a potential Gen 2 model.
