The STEELFLY TARGET BOX 404 is a compact modular air rifle target system that delivers the same premium modular concept as the TARGET BOX 413 in a smaller and more affordable package. Built around the patented STEELFLY HookHole® mounting system, it allows shooters to reposition targets and create new shooting layouts quickly without using tools.

TARGET BOX 404 supports up to three interchangeable hanging targets and features a front mount for a 14 × 14 cm airgun paper target, combining precision paper target practice with reactive steel targets.

Designed as part of the STEELFLY modular ecosystem, the TARGET BOX 404 can be expanded with Upgrade Kits and compatible accessories as shooting skills develop. Manufactured from precision laser-cut steel with electrochemically applied zinc and black zinc protection, it provides excellent durability for both indoor and outdoor use while safely collecting lead pellets.
