FMA AN/PEQ-15 Battery Box — Tan

The FMA battery box in AN/PEQ-15 format is a rigid housing designed to hold the battery of AEG rifles while keeping a compact profile that fits naturally into a tactical weapon setup. At 74x59x15 mm, it mounts directly onto any RIS/Picatinny rail with no additional adapters required.

Compared to improvised solutions, the main advantage is tidy cable management: the battery stays protected and secure during use, with no risk of disconnection from impacts or movement. The 15 mm low-profile body limits lateral bulk and does not interfere with other accessories mounted on the top or side rails.

The form factor closely replicates the footprint of an AN/PEQ-15 designator, which allows the line of sight to remain clear and the box to integrate into the overall setup without looking out of place. It performs no optical or laser function: it is solely a battery housing.
