Here at Nemesis Defense we think this is a great little sight for the money. Not to mention it’s a very slim design because the battery is mounted in the actual base mount of the optic. A lot of like competitor optics have the battery housing mounted on the side which can obstruct vision down range.

The ROMEO5 X is a compact, closed red dot sight for use with modern sporting rifles, carbines, shotguns and air rifles. It features a crisp, 2 MOA dot reticle for rapid target acquisition in any situation. The sight comes with a modular mounting system supporting either 1.41″ absolute co-witness or 1.63″ 1/3 lower co-witness sight height, and attaching with a Torx cross-bolt mount. The ROMEO5 X features MOTAC and runs off a single AAA battery providing over 50,000 hours of runtime during normal use.
