The Vector Optics Frenzy FA Enclosed Green Dot Sight features a rugged, fully enclosed emitter housing that completely shields the internal optics from rain, dust, mud, and debris. Engineered with a multi-reticle configuration, shooters can quickly switch between a precise 2 MOA dot, a 46 MOA speed ring, or a comprehensive crosshair layout to suit varying tactical and competition environments. The crisp, vivid green illumination provides an exceptionally sharp sight picture that drastically reduces reticle bursting for users with astigmatisms. Built to withstand punishing reciprocal forces up to 1500G, its tough 7075-T6 aluminum alloy structure relies on a side-loading CR2032 compartment for easy battery changes without disturbing zero. Complete with an intelligent 10-minute motion sensor sleep mode, 9 daylight settings, and 2 night-vision modes, this high-performance optic utilizes a VOD footprint natively compatible with the ACRO mounting standard.
