Small, sealed and built for bad decisions by the weather.
The Frenzy FA is Vector Optics’ answer to shooters who are done with open emitters filling up with rain, dust and whatever else the day throws at them. It’s an enclosed reflex sight with an ACRO/VOD footprint, designed to live happily on pistols or compact builds where reliability matters more than saving a few grams. The footprint stays small, the housing stays sealed, and the dot stays visible when conditions are doing their best to ruin your session.

The 3MOA red dot strikes the sensible middle ground between speed and precision, backed by 9 daylight brightness levels plus 2 night vision settings. The window is compact but usable, with slim edges that keep the sight picture open rather than boxed in. A motion sensor handles power automatically, so you don’t drain the battery by forgetting to switch it off, and the side-loading tray means battery swaps don’t require re-zeroing. Simple, practical, and aimed at shooters who actually use their gear.
