Features of Gideon Optics Rock Red Dot Reflex Sights

  • Choose from a red or green color for your combination 65mm circle and 3 MOA dot reticle.
  • Adjustable at 1 MOA per click through a 45-click range for both windage and elevation (90 total).
  • User-adjustable brightness settings allow for ten gradients, 8 for normal light and two that are night vision compatible.
  • Ready for mounting on standard RMR footprints or with the included low-profile 1913 Picatinny mount.
  • A single CR-1632 3V lithium battery can provide up to 50,000 hours of service life thanks to an auto-engaging low-power mode that turns off the reticle at 225 minutes of inactivity but reengages when the weapon is drawn or moved thanks to our shake-to-awake sensors.
  • Changing the battery is easy thanks to a top-loading battery tray that does not require removal from the weapon or re-zeroing of the sight.
  • The housing is field ready with an IPX7 waterproof and shockproof design and 7075-T6 aluminum alloy housing.
  • Measures 45mm x 32mm x 26.4mm (LxWxH) and weighs around one oz. to keep your firearm feeling light and reactive.
