The Swampfox Sentinel II 1×20 Micro Green Dot Sight (brand part no. SNL2120GMS) is a Swampfox micro pistol optic built for concealed carry on slimline optics-ready pistols. It keeps the standard RMSc footprint but adds a larger 20mm window than the first-generation optic. The dot is a 3 MOA green, and this version ships with the standard blackout rear sight guide, a patented removable guide set in front of the window that gives backup support on micro pistols that give up their rear iron sights. Shake ‘N Wake handles the power for you, which suits a gun that lives in a holster most of the day. A 7075-T6 aluminum body keeps the package slim and tough.
