Overview

Designed for full-sized pistol use, this open reflex sight pairs a 2 MOA dot with a 32 MOA circle in a red reticle for flexible aiming. It offers a parallax-free sight picture, a compact 0.63 x 0.91 window, and power from both solar and a CR1632 battery. Lock Mode helps prevent unintended button changes, which is useful when the optic is carried or handled frequently. The 7075 T6 aluminum housing with anodized finish gives it a straightforward, duty-oriented build without adding unnecessary bulk.

Considerations & Trade-offs

  • Designed for full-sized pistol applications, so it may not be the right fit for smaller platforms or non-pistol setups.
  • The open reflex design and 0.63 x 0.91 window keep the sight compact, but the viewing area is still limited compared with larger optics.
  • Lock Mode helps prevent inadvertent button changes, but it also means settings are intentionally locked until you disengage the feature.
  • Powered by both solar and a CR1632 battery, so battery management still matters even with solar support.
