MM Firefly Shell Lifter Spring

A small but essential part: the return spring that resets the Firefly's shell lifter after every pump stroke. Without it, the lifter will not spring back into position to pick up the next shell, and your pump action stops feeding properly. It is a tiny component that is easy to lose during a strip-down or a cleaning session, and it is exactly the kind of part that fails silently until your Firefly suddenly will not cycle right.

This listing is the direct stock replacement for that spring, cheap enough to keep a couple as spares in your parts box so a lost or fatigued spring does not take your Firefly out of action. Pair it with the Shell Lifter itself if you are doing a full internals refresh rather than a single-part fix.
