The Monstrum Ghost 3x Magnifier is built for use with red dot sights, providing a secondary 3x magnified sight picture. The flip-to-side mount with quick engage mechanism allows for rapid transition between red dot usage with or without magnification. Built with the Monstrum proprietary Helios3 glass prism optical system, the Ghost 3x Magnifier refracts light with a glass prism providing a crisper sight picture in a more compact form factor than competing magnifiers.
