The Konus Sight Pro Fission 2.0 Red Dot Sight is extremely compact so it will add minimal weight to your tactical rig. The sight is ideal for use on handguns or shotguns, and it is also a great choice to mount to the side of a scope for CQB situations. The sight features a 4 MOA dot, and the user can switch between red or green illumination depending on the situation. The 2.0 has been upgraded with an on/off button verses a switch and has five different intensities for light conditions. Included with the Sight Pro Fission 2.0 are a screwdriver for windage and elevation adjustments, a cover, a revolving windage and elevation adjustment dial and Allen wrenches for mounting and changing the battery.
