MM Firefly Magazine Follower

The MM Firefly Magazine Follower is the small internal component that sits inside the Firefly's magazine tube, riding along the tube spring to push shells forward toward the breech as you cycle the pump. It's an easy part to misplace during a full teardown or cleaning session, and without it the magazine tube won't feed shells reliably — this listing is the direct factory replacement for the Firefly.

Since it's built to the stock Firefly magazine tube dimensions, it drops straight back into place alongside your magazine tube spring, no fitting or trimming required. If your Firefly has started short-stroking or failing to feed the next shell and you've already ruled out the spring, a missing or worn follower is a good place to check next.
