The Shield Sights RMS2 Glass Edition Reflex Sight, 4 MOA (Shield Sights part no. RMS2-4MOA-GLASS) is small enough to sit discreetly on a carry pistol, yet tough enough to withstand hard recoil without shifting zero. Machined from aerospace-grade aluminum, it uses super-fast automatic brightness adjustment so the shooter can stay focused on the target instead of fiddling with settings. Removing the battery drawer found on the original RMS let Shield strengthen the housing and fit newer electronics, and the low-profile design pairs with a matching Glock MOS plate to co-witness with standard iron sights, no suppressor-height sights required. The Glass Edition upgrades the lens to a scratch-resistant, ultra-clear glass window paired with improved battery contacts.
