The Swampfox Optics Sentinel II, 1x20mm, micro green dot with standard blackout rear (Swampfox part no. SNL2120GMS), showcases a fusion of advanced features in a design built for serious concealed carry use. This micro pistol dot sight keeps the standardized RMSc footprint and its familiar slimline profile while maximizing visibility with a larger 20mm objective window, an improvement over the 16mm lens found on the first-generation Sentinel. Its most unique feature is a patented, removable rear sight guide installed in front of the window, giving backup support for micro pistols that sacrifice their rear iron sights for dot sight compatibility. Swampfox’s Shake N’ Wake auto on/off feature keeps the sight grab-and-go ready.
