Sig Sauer ROMEO-M17 Mil-Spec Enclosed Red Dot (M17 M18 ONLY)

The M17 and M18 pistols have been selected by the US Military as the official sidearm and the ROMEO-M17 is the only optic that is truly designed specifically for this pistol.  All other optics have many disadvantages and make several compromises.  The ROMEO-M17 does not.  This is an American-built MIL-SPEC red dot truly worthy of the SIG SAUER name.

Please Note – The ROMEO-M17 pistol red dot sight utilizes SIG SAUER'S proprietary SIG-LOC mounting interface and only fits SIG SAUER M17/M18 military issue and commemorative pistols with a single optics plate mounting screw. This sight will not fit any other pistols.

  • A fully enclosed sealed and purged optical system for ultimate protection from the elements
  • Mounts from underneath the pistol slide re-using the MHS pistol rear sight block and sight block screw
  • 7075 Aluminum housing
  • Integrated gas deflector on the front of the housing
  • Machined anti-reflection grooves on all rear surfaces for reduced glare
  • Extremely low deck height allowing a full sight picture and co-witness with standard-height sights
  • SIG-LOC™ (SIG Leverage Optimizing Connection) proprietary mounting interface for the ultimate optic/pistol lockup.
  • A high-efficiency point source LED emitter with 2 MOA dot/32 MOA circle reticle.  The reticles are independently selectable (circle only dot only or circle/dot combination).
  • Independent brightness adjustment buttons that are recessed within a protective plate which can be activated even with gloves on. Buttons have bump features above UP and below DOWN so they can be determined by feel.
  • 15 brightness settings with 3 of the settings optimized for use with Gen 3+ NV devices
  • A side-mounted CR2032 battery compartment with a threaded battery cap for easy battery changes without the need to remove the optic from the firearm.  The cap is slotted and knurled for use with or without tools.
  • Minimum continuous runtime of 20000 hours at medium brightness setting
  • 2 drainage holes machined in the sides of the housing just behind the rear sealed window to allow pooled liquid to escape when the optic goes from a vertical position (such as in a holster) to a horizontal position (such as shooting)
  • Windage and elevation adjustments have tactile clicks.  Adjustment screws are slotted for use with any small flat-blade tool.  Adjustment resolution is 1.5 MOA per click.
  • MOTAC (Motion Activated Illumination)
  • MAGNETAC (Magnetic Activation)
  • D.A.R.C. (Dark Adaptive Reticles & Coatings)
  • Designed developed tested and fully assembled in the USA
