MM Firefly Catch Plate

The catch plate is part of the Firefly's pump-action lockup, working alongside the catch spring to hold the pump grip in position at the front and back of its stroke so the blaster primes and locks the same way every time. It's a wear part that can crack under repeated pump cycles, and the MM Firefly Catch Plate is the direct stock replacement, built to the original spec so it seats back into the shell exactly where the factory part did.

If your Firefly's pump has started feeling loose, failing to catch at the end of the stroke, or rattling in the shell, a cracked catch plate is a likely cause, and swapping it in restores the pump action to normal without touching any other part of the blaster.
