Shield Sights RMSd Glass Edition Features The Shield Sights RMSd Glass Edition centers on a D-shaped scratch-resistant ultra clear glass lens that delivers an unobstructed view of the target with no red reflective filter to create a visual signature. The 4 MOA dot reticle is bright enough for fast acquisition up close while staying precise enough for more deliberate shots at distance. A variable intensity drive circuit senses ambient light and automatically adjusts LED output keeping the dot visible against bright backgrounds or dim rooms without any manual input from the shooter. The housing is machined from aerospace grade aluminum to tight tolerances giving the sight a rigid recoil resistant structure despite its compact and discreet size. Shield s own mounting footprint lets the RMSd Glass Edition co-witness with standard iron sights on many Glock pistols cutting training time by letting shooters transition naturally between the dot and factory sights. A side accessible battery drawer means the single CR1632 battery can be swapped without ever removing the sight from the slide preserving zero between changes. That battery is rated for roughly 9 000 hours of runtime in average daylight thanks to the automatic brightness circuit so the sight can be left powered on and ready without concern for rundown. Finished in an anodized matte black and weighing only 0.65 oz the Shield Sights RMSd Glass Edition is a rugged low profile optic for sale at GrabAGun built for concealed carry and duty pistols alike.
