Regardless of the scenario the EOTech EXPS2-2 Holographic Sight, (2) dot Ballistic Reticle, w/ 3X Magnifier and FTS Mount (MPO-III) provides an unparalleled advantage when transitioning from short to long range shooting. The Eotech EXPS2-2 offers true 2 eyes open shooting, a transversly mounted lithium 123 battery, 7 mm raised base offering iron sight access, and easy to adjust side buttons. The 3x Eotech magnifier with Flip-to-Side (FTS) mount provides superior light transmission and the large field of view puts the competition to shame. Both units offer quick release throw levers for easy attachment and removal.
