Pistol Compatibility Checker
Check if your pistol mounts the MERCURY™ Reflex Sight direct, needs an adapter plate, or requires a slide cut.
We may not have this model listed yet. If your slide has a factory RMR optics cut, MERCURY™ will mount directly. If not, a slide cut or aftermarket optics-ready slide is needed. Contact us for a definitive answer on your specific pistol.

MERCURY™ Fall Bundle, Save $100
The Mercury is built for speed: both eyes open, dot on target, shot broken. For fall, we're taking $80 off the sight and giving you the cover free. The cover keeps the window clean between strings, so the sight is ready the moment you pull it out of the bag.
Two parts. One box. One price.
What's in the Bundle?
MERCURY™ Reflex Sight ($80 off)
Open-emitter red dot with four selectable reticles and nine brightness levels, eight for daylight and one for night vision. Motion-activated wake, so it's on before you are. Three-year battery life on a single top-loading CR2032, IP68 waterproof, RMR-compatible footprint that fits most existing mounts and slides. Designed, assembled, and tested in Texas.
Silicone Cover for the MERCURY™ (FREE)
Keeps dust, rain, and range grit off the window between strings.
Choose your setup: 3 MOA Red Dot or 3 MOA Green Dot.
Bought separately: $269.95
Fall Bundle price: $169.95
You save $100: $80 off the Mercury, plus the cover on us.
The Mercury is a 1x open-emitter sight. There's no magnification, and the emitter is exposed the same way an RMR's is. In exchange, you get a sight that wakes when you move, runs three years on one battery, and costs half what the name on the box usually costs.
