Firearm Optics That Use CR2032 Batteries
Many popular red dots, reflex sights, and prism optics rely on the CR2032:
Holosun – Most standard-size and micro-reflex red dots (such as the HE507C, HS503, and many open/closed emitter models) use a side- or tray-mounted CR2032.
Trijicon – Certain electronic red dots and hybrid optics (like select Trijicon models) use CR2032 cells for reticle illumination.
SIG Sauer Electro-Optics – Many Romeo-series red dots (such as select Romeo5 or open-reflex lines) run on a top- or side-loading CR2032 battery.
Primary Arms – Micro reflex and illuminated prism/red dot optics frequently utilize the CR2032 footprint.
Vortex Optics – Many Crossfire, Venom, and Viper red dot sights use a top- or bottom-accessed CR2032 battery.
Aimpoint – While larger duty sights (like the PRO or CompM4) use 1/3N or AA batteries, select micro/compact units or specific configurations utilize coin-style lithium cells
