Overview

The INFITAC Fast Mini FMP13 is a compact thermal sight with a standard RMR footprint. Its 256x192 sensor, 13mm F1.0 objective, 60Hz refresh rate, and 1.4-inch 360x300 display place a selectable reticle over a thermal image. The sight uses a 0.5x base view with 1x and 2x digital zoom, four color palettes, and a CR2 battery rated for up to 5 hours.

The FMP13 can mount on an RMR-cut pistol slide or a rifle offset mount, but its role changes by host. It is better suited as a thermal offset optic beside an LPVO or on an RMR offset mount than as a pistol primary because it has no see-through daytime red-dot mode or co-witness. The package includes an RMR adapter plate, two CR2 batteries, and two heated zeroing targets.

Cons

−Real-world battery life ran somewhat shorter than the 5-hour rating in hands-on testing
−Not see-through, so there is no co-witness with backup irons or daytime red-dot mode, which makes it a better rifle offset optic than a pistol primary
−Single CR2 with up to 5 hr rated runtime is short next to conventional red dots
−4 oz is heavy for a pistol slide next to typical RMR-footprint red dots
−256x192 sensor is entry-level thermal resolution
