Vortex Optics VMX3 3X Red Dot Magnifier
The Vortex Optics VMX3 is a fixed 3x magnifier designed to run behind a 1x red dot sight when you want additional magnification without changing your primary optic. Fully multi-coated lenses support strong light transmission and a clean sight picture.
Built around a hard-coat anodized, machined-aluminum housing, the VMX3 is nitrogen purged and O-ring sealed for waterproof and fogproof performance.
