Eotech has done it again by making the best even better. Offering true 2 eyes open shooting, a transversly mounted lithium 123 battery, and 7 mm raised base offering iron sight access, the new Extreme-XPS (EXPS) features easy to adjust side buttons and a single, quick release throw lever for easy attachment and removal.
Reticle is a 65MOA circle with 1 MOA aiming dot
Single transverse 123 battery to reduce sight length
Shortened base only requires at most 2 3/4 inch of rail space compared to the 4 inch N battery sights
Battery cap and latch are eliminated and replaced with a simple O-ring, tethered cap; better sealing is achieved
Battery compartment is now separated from the base to allow it to hover over the delta ring of the rifle
Average battery life at brightness level 12 is roughly 500-600 hours, 3X battery life of N cell sights
Side buttons, NV compatible with a single quick detach throw lever
