The VMX-3T Magnifier and Flip Mount combo adds a 3x magnification to your rifle's red dot sight. Simple, fast, and effective, the push button design engages and disengages the flip mount allowing the magnifier to lock in at your desired position. The lenses are fully multi-coated maximizing resolution, light gathering capability, and color fidelity. The VMX-3T gives you a generous 3.25 inches of eye relief with a 38.2 foot field of view at 100 yards.
