Considerations & Trade-offs

Designed for subcompact pistol applications, so the compact window size may be a limiting factor for users who prefer a larger sight picture.
The optic uses a CR1632 battery, which means battery management is part of regular setup and maintenance.
Lock Mode helps prevent inadvertent setting changes, but it also adds a step if you want to adjust the controls quickly.
The 2 MOA dot and 32 MOA circle reticle offers flexibility, but some users may prefer a simpler single-dot sight picture.
