The Shield Sights Mini RMSd Reflex Red Dot Sight is 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 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 and coupled with the Shield Sights low profile Glock mount, the RMS sits so low that the sight will co-witness without the need for suppressor sights.
