Gideon Optics ROCK (RMR Compatible) Green Circle Dot Sight

Features a 15.5mm x 22mm lens with unlimited eye relief and parallax-free operation out to 33 yards for faster and more accurate target acquisition in dynamic tactical situations without occluding your field of view. Choose from a red or green illumination and your choice of static reticle: a large 45MOA circle surrounding a 3MOA dot, or a single 3MOA dot 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 seconds 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 1.8 oz. to keep your firearm feeling light and reactive. Backed by a lifetime warranty that covers almost everything short of intentional damage. If it stops working for any other reason, Gideon Optics replace it.
