MERCURY™ Reflex Sight
The Mercury™ Reflex Sight is built for shooters who demand speed, precision, and modern design. Engineered with a rugged IP68 waterproof housing, Mercury™ performs in the harshest conditions—up to 3 M for 30 minutes.
The Mercury™ Reflex Sight is proudly designed, assembled and tested in USA
With 4 selectable reticle options and 9 total brightness levels (8 daylight + 1 Night Vision), you get a sight that adapts instantly to every scenario.
Mercury™ features motion activation, waking the optic when moved and powering down after 5 minutes of no movement. Combined with a top-loading CR2032 battery and up to 3 years of battery life, you get maximum uptime without removing the optic for battery swaps.
The RMR footprint ensures compatibility with a wide range of mounts and plates, while crisp 1 MOA adjustments let you zero quickly and precisely.
