Crafted for precision and built to stand guard, the Swampfox Sentinel II showcases a fusion of advanced features in a sleek, cohesive design. Designed for concealed carry, this micro pistol dot sight maintains the standardized RMSc footprint and its familiar slimline profile while maximizing visibility with a larger 20mm window. Its most unique feature is the patented removable rear sight guide installed in front of the window. This guide provides backup support for micro pistols that sacrifice their rear iron sights for dot sight compatibility. Sentinel II displays a 3 MOA dot in either red or green illumination and is equipped with Swampfox's Shake N' Wake auto on/off feature for grab-and-go readiness.
