Primary Arms Optics has unveiled the new SLx RS-10R Mini Reflex Sight, which debuted at SHOT Show 2025. This compact sight is designed for pistols and is compatible with the popular RMR footprint standard, making it compatible with a variety of optical frames and mounts.
The SLx RS-10R is made of lightweight and durable 7075 aluminum. It features a 23x19 mm multi-coated lens and a side compartment for a CR1632 battery for easy replacement. The sight weighs just 31 grams and, thanks to AutoLive® technology, can operate for up to 40,000 hours, automatically turning on with movement and conserving power when idle. The manufacturer emphasizes that the design combines durability, easy operation, and a long operating time, making it a practical choice for both professionals and civilian shooters.
The new model offers a 3 MOA reticle, considered the optimal compromise between precision and target acquisition speed. The illumination is designed to be clearly visible even in direct sunlight ("Daylight Visible"). As Primary Arms emphasizes, the decision to use the RMR footprint was a response to feedback from users of the previous SLx RS-10 version, which increases mounting flexibility without sacrificing durability or affordability.
