Primary Arms SLX RS-10R Mini Green Dot Reflex Sight 23mm 3 MOA Green Dot Black RMR Footprint 810057 UPC 810178480524
Product Description
The Primary Arms SLx RS-10R Mini Green Dot Reflex Sight (810057) is a rugged, micro electronic aiming optic built to deliver rapid target acquisition and precision accuracy across handguns, tactical rifles, shotguns, and offset optic mounts. Part of Primary Arms' famous SLx optic line—known for rigorous field testing and duty-grade reliability—the RS-10R combines a crisp 3 MOA green dot reticle with an ultra-clear 23mm objective lens for an expansive, unobstructed field of view.
Precision CNC-machined from lightweight 7075-T6 billet aluminum, the optic body features a hardcoat anodized matte black finish designed to absorb severe slide acceleration recoil, drop impacts, and environmental abrasion. Unlike traditional red dots, the high-efficiency green LED reticle is exceptionally easy for the human eye to pick up under harsh sunlight and bright background conditions, making it an ideal choice for fast-action shooting and shooters with astigmatism.
Engineered with the industry-standard Trijicon RMR mounting footprint, the RS-10R mounts directly onto optics-ready pistol slides and aftermarket adapter plates. Equipped with side-loading battery access, tactile push-button brightness controls, and AutoLive motion-sensing illumination technology, the SLx RS-10R (810057) powers down during inactivity and activates instantly upon movement, ensuring your optic is always staged and ready for service.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits any slide cut, adapter plate, or Picatinny mount designed for the standard Trijicon RMR mounting footprint. Suitable for full-size, compact, and crossover optic-ready handguns, as well as 45-degree offset or primary carbine mounts.
- Perform a complete firearm safety check: drop the magazine, lock the slide or action rearward, and visually inspect the chamber to verify zero live rounds are present.
- Clean the slide optic pocket and ensure thread holes are clean and free of old threadlocker or oil residue.
- Place the SLx RS-10R onto the RMR index posts, ensuring the optic housing sits completely flush against the mounting surface.
- Apply a small drop of medium-strength threadlocker (Blue Loctite 242 or Rocksett) to the proper length mounting screws.
- Torque mounting screws evenly to 12–15 in-lbs using a calibrated inch-pound torque wrench to prevent stripping or optic binding.
- Power on the optic, adjust brightness settings, and perform a function test before live-fire range zeroing.
