The next evolution in mini red dot sights. Small enough to fit discreetly on any gun, tough enough to withstand the harshest recoil and light enough that you won't even feel it's there. The Shield RMS is machined from strong aerospace grade aluminium. It has super-fast automatic brightness adjustment to adapt to your environment allowing you to concentrate on the target and the quick release side accessible battery drawer means you can change the battery without the need to dismount. Its stunning, low profile design makes it an ideal optic for any custom pistol build. Screws are not included. Mfg: Shield Sights Ltd. Screws are not included.
