The EOTech EXPS3 Transverse Law Enforcement and Military Holographic Red Dot Sight is the most compact sight available from EOTech that is night vision compatible. It runs on a single CR123A battery which provides up to 1000 hours of continuous runtime at setting 12. The EXPS leaves tons of rail space available for mounting flip-up iron sights or a magnifier and the integral picatinny mount allows for use on either a Weaver or Picatinny-style rail. The EOTech EXPS3 is compatible with night vision devices.
