The Meprolight Mepro X3 Magnifying Scope with Tactical Flip Mount MOUNT MX3-T offers 3X magnification to enhance the precision and effectiveness of Microlight’s reflex/red dot sights (MEPRO M21, MEPRO MOR, MEPRO M5 RDS) and other optical sights, with no need to re-zero the sights. The MEPRO MX3-T attaches to the Picatinny rail immediately behind the reflex sight and features a Tactical Flip Mount adapter. When not being used, it is offset to the right side and can be easily flipped back into place when the shooter needs to engage targets at longer distances. The MEPRO MX3-T is rugged, compact, lightweight,  and manufactured to the highest military standards to assure years of reliable operation.
