Overview
A low-profile pistol red dot sight with a 3 MOA reticle, RMR mounting footprint, motion-sensor shake-awake, and IPX6 water resistance, sized for full-size handgun slides.
Reviewers frame it as a budget alternative to pricier optics like the Trijicon SRO or Holosun, citing the same RMR footprint and a comparably large viewing window. Feedback is consistent on holding zero across hundreds of rounds, though several buyers received units without a battery included, and a couple arrived without functioning shake-awake.
- 3 MOA reticle plus crosshair and combination options
- RMR mounting footprint, 7.2mm low-profile height
- Motion-sensor shake-awake rated for 50,000 hours battery life
- IPX6 water and shock resistance rated for 9mm, 45 ACP and 12 gauge recoil
What buyers say
From Amazon customer reviews.
Reviewers who mounted this on pistols and even a rifle report it held zero through 200 to 400 rounds with a crisp, clear dot and a large sight window that speeds target acquisition. Recurring complaints are a missing battery in the box, adjustment clicks that give no audible or tactile feedback, and inconsistent shake-awake behavior on some units.
