Collimator Primary Arms SLx RS-10 1x23 Mini Reflex 3 MOA

Primary Arms SLx RS-10 is a small, ultra-light pistol red-dot device. Simple, functional and rugged, it helps improve both static and dynamic shooting skills. To ensure fast and precise target acquisition in any lighting, it uses a 3 MOA dot with adjustable illumination. The device features low-light modes suitable for night-vision use. An anti-reflective coating provides good light transmission and a clear, color-accurate image. The housing is made from 7075 aluminum. The unit includes a Docter/Noblex footprint* and an adapter to mount on Glock pistols.

Long battery life and AutoLive

The Primary Arms SLx RS-10 stands out with an impressive runtime on a single CR2032 battery — up to 40,000 hours. This efficiency is provided in part by the AutoLive system, which powers down illumination when no motion is detected and instantly reactivates it when the firearm is moved. This is practical and convenient, significantly extending battery life and reducing running costs.
