Product Details
The Primary Arms SLx MD-21 Push Button Microdot delivers a clean 2 MOA red dot in a compact 21mm aluminum housing with unlimited eye relief for instinctive target acquisition on rifles, shotguns, or pistol-caliber carbines. AutoLive motion-sensing technology automatically activates the dot when the firearm is picked up and powers down when it is set aside, extending battery runtime to over 40,000 hours on a single CR2032 cell. The T1-compatible footprint ensures broad mount compatibility across popular picatinny and offset options. Built from 6061-T6 aluminum with an IP67 waterproof rating, it is designed for hard everyday use without fuss.
