The STEELFLY TARGET FRAME 504 is a versatile air rifle target system designed for shooters who want a modular platform that can grow with their skills. Built around the patented STEELFLY HookHole® mounting system, it allows users to quickly reposition targets, change target sizes and shapes, and create new shooting layouts without special tools.

Unlike conventional fixed steel targets, TARGET FRAME 504 is a true modular shooting target system that adapts to different training styles and experience levels. Whether used for recreational shooting, structured practice or precision marksmanship training, the system can be customized with interchangeable target plates, obstacle modules and accessories to create virtually unlimited shooting scenarios.

Designed for year-round outdoor use, the frame is manufactured from precision laser-cut steel and protected with electro-galvanized zinc and black zinc finishes, providing significantly greater corrosion resistance and durability than traditional painted steel targets.

As your skills improve, TARGET FRAME 504 can be expanded with shooting training target upgrade modules and transformed with STEELFLY Conversion Kits into a dedicated precision airgun target system, allowing shooters to continuously increase the challenge and push the limits of their accuracy.
