Sig Sauer ROMEO-X SIG-LOC PRO Enclosed Circle Dot Sight

The Sig Sauer ROMEO-X SIG-LOC PRO Enclosed Circle Dot Sight is a MIL-SPEC reflex optic built for performance and durability. With its Circle/Dot reticle, you get a precise 2 MOA dot inside a 32 MOA circle for fast target acquisition and accurate aiming. The fully enclosed optical system is sealed and purged, protecting against moisture and debris, while the SIG-LOC PRO footprint ensures a strong, low-profile mount—note that this mount is not compatible with older slide cuts. Operating under MOTAC™ and MAGNETAC™ technologies, it powers with a side-load CR1632 battery and offers up to 20,000 hours of runtime at medium brightness.
