MM Firefly Magazine Cap

The MM Firefly Magazine Cap is the factory-spec replacement for the magazine tube cap on the Monkee Mods Firefly. It sits at the end of the magazine tube, keeping the tube spring and follower contained under tension, and it's a common part to need whenever a Firefly's stock cap has cracked from regular pump-action use. Rather than sourcing an aftermarket workaround, this is the same part built to the original Firefly spec, so fitment is a direct swap onto your magazine tube with no modification needed.

It's also available in three colour options beyond the standard cap: Yellow, Bright Orange, and Classic Orange, so you can match or contrast the rest of your Firefly build when you replace a cracked one.
