MM Firefly O-Ring Set

Sold as a set, the MM Firefly O-Ring Set covers the stock O-rings used throughout the Monkee Mods Firefly, the small rubber seals that keep air from leaking past fittings and moving parts inside the blaster. O-rings are a wear item on any springer or pump-action platform — they compress, take heat, and eventually lose their seal, which shows up as reduced power or inconsistent shots even when every other part is in good shape.

Rather than tracking down individual sizes, this set gives you the O-rings you need on hand for a Firefly rebuild or routine maintenance, matched to the original Firefly spec so replacement is a straightforward swap of old for new during your next strip-down.
