This listing is for the 3 MOA RED DOT OPTION.


There are large window RMR Optics, and then there’s the Omega red dot sight. Featuring a huge lens window and competition-ready features, the Omega is designed to speed up target acquisition and improve accuracy without costing you an arm and a leg. We’ve engineered the features you need, like a dual-MOA circle/dot reticle, adjustable brightness, and a long battery life that’s extended by our innovative low-power mode with shake-to-awake technology, then matched that engineering to materials that are ready for the rigors of field use in dynamic tactical situations. Shoot better with an extra-large window dot sight from a company you can count on to have your six.


Big Sight Picture, Small Groups: 

The large lens on the Omega red dot sight gives you a big sight picture without blocking out your field of view–always dangerous in a duty or defensive tactical situation. This makes it the perfect pistol optic choice for shooting competitions, range work, as a duty weapon, or as a backup reflex sight on larger firearms.

  • The 7075-T6 aluminum housing is made from the same material often used in components for the m-16 rifle and other firearms. This aluminum alloy is known for its durability in the field under harsh conditions.
  • The massive 22.3mm tall by 27mm wide lens is parallax free to 33 yards and features Circle-Dot and Dot ONLY options.
  • Reticle Options:
    • RED 65MOA Circle with a 3MOA Dot
    • RED 3MOA Dot
    • GREEN 3MOA Dot
  • Elevation and windage are adjustable for a total of 90 MOA (45 MOA each) at 1 MOA per click.
  • Designed to fit the popular Trijicon RMR optic pattern common on many handguns. A low-profile 1913 Picatinny mount is also included for mounting on compatible rifles, carbines, PCC weapons, or as a 45-degree offset backup reflex sight.
  • This sight offers unlimited eye relief for quick and accurate targeting.
  • Choose from 10 brightness settings, including 8 for normal light and two night vision compatible settings.
  • A battery-extending low-power mode turns off your emitter after 225 seconds without motion. Any movement, from drawing to a quick wrist shake, reactivates your reticle in milliseconds.
  • The Omega red dot sight is powered by a single CR-1632 3V lithium-ion battery that’s easily changeable without removing or re-zeroing the sight, thanks to a convenient top-loading battery tray. Expect a single battery to give you up to 50,000 hours of service life thanks to our energy-efficient features and design.
  • Weighs approximately 1 oz. and measures 45mm x 32mm x 26.4mm (LxWxH).
  • We made this sight shockproof and IPX7 waterproof, so it’s ready for whatever you throw at it.
  • Gideon Optics’ sights are backed by a three-year warranty that replaces your sight if it stops working for any reason short of intentional damage.
