Trijicon's MGRS is a non-magnified optic that mounts to both the M2 and the M240 machine guns. The Trijicon MGRS is intended to aid the machine gunner in rapid target acquisition and engagement that will allow to keep both eyes open from a natural shooting position. Accuracy is enhanced by use of the machine gun specific interchangable Range Dials and performance is assured with a strong 7075-T6 forged aluminum housing.
