The Model Eotech 552 HOLOgraphic Weapon Sight (HWS) is fully compatible with all generation levels of night vision intensifier tubes. A special night vision (NV) setting of 551 and 552 EOTech sights allows the operator to immediately drop the brightness intensity of the holographic reticle to eliminate any "halo" effect while viewing through an image intensifier tube. The M550 can be positioned in tandem behind night vision intensifiers without any "bloom" of the target area. Eotech product reviews from our US Army customers have been great! Now Eotech holosight operators can combine the proven night vision technological advantage with a superior close quarters weapon optic to achieve greatly enhanced weapon aiming - in complete darkness.
