Upgrade your FX Panthera, Dynamic, or King with the magazine it deserves.
Designed to outperform the factory magazine, this custom-engineered upgrade solves the biggest complaints shooters have with the original: ease of loading and cycling reliability.
Whether you are competing in PRS or hunting, our Magnetic Lid system snaps securely in place, making mid-session reloads quick and frustration-free.

Choose Your Internal Depth
Unlike "one-size-fits-all" magazines, we offer two internal configurations to match your specific ammunition. Choosing the right one ensures the smoothest possible cycling.
-
Standard (13.30mm):
The versatile choice. Designed for long slugs and heavy, high-BC projectiles that require maximum internal clearance.
-
Reduced (11.90mm):
The "Reliability King." By reducing internal dead space, this version prevents shorter projectiles (like standard pellets) from tilting or "nose-diving" during cycling. It also eliminates the "maraca effect" by keeping rounds tight, so your magazine stays quiet in the field.
