The PMGS is a patented red/green reflex dot sight specifically designed and built for the M2 .50 Caliber, M-134 Minigun, M60, and M240 Machine Guns, and MK19 40 mm automatic grenade launcher. A third-generation machine gun sight offers a very large field of view design with an unequaled 80×50 mm lens that provides rapid acquisition and tracking of stationary and moving targets, it also provides pinpoint accuracy which ensures every round is on target to suppress the enemy fire faster, reduce collateral damage, and drastically reduce ammunition consumption. The sight features a removable LED light source module with stadia line-style reticle that improves accuracy by eliminating the need for sighting guesswork. Using hash marks, the gunner can estimate the range, select the proper BDC mark, place the dot on the target and pull the trigger. Simple operation prevents combat confusion and distraction.
