Meprolight’s MMX3 Magnifier is an ideal option for extending your accurate shooting range. The MMX3 is compatible with virtually any red dot sight and folds to the side when not in use, allowing to use the red dot to engage targets at close range. For targets at extended distances, the MMX3 can instantly deploy and provide 3x power magnification without the need to re-zero the red dot. Like all of Meprolight’s premium optics, the MMX3 utilize high-transparency glass and are built to withstand shocks, impacts, and sustained recoil.
