The SightPro Fission 2.0 is a micro-compact electronic dot sight. If you’re looking to minimize weight, then this 1.76 oz. device is exactly what’s needed. Perfect for use on handguns & shotguns, but also a terrific choice to mount on the side of a scope for CQ situations. The 4 MOA dot can be illuminated with 5 intensity settings for all lighting conditions. The strategically placed push button control switch separates the Fission from other models in the market by keeping your battery life running at optimum performance while staying clear of the shooters line of sight. The full body cover keeps your scope clean and in tip-top conditiion when not in use.
