The SIG ROMEO-X Enclosed is a compact red dot that utilizes the popular Shield RMS-c footprint to attach to many of the popular optic-ready slimline handguns on the market. It features a side-loading CR1632 battery that offers 20,000 hours of operation, 15 brightness settings with 3 night vision modes, and a beryllium copper flexure arm that increases zero retention and overall durability. Because of this new flexure arm design and the side-loading battery, the ROMEO-X has a very low deck height, allowing for co-witness with most standard-height irons.
