MM Firefly Breech

The breech is where the shell locks into place before firing on the Monkee Mods Firefly, and it takes a lot of repeated stress from loading and extraction cycles — which is exactly why it's one of the more common parts to crack or wear out over time. The MM Firefly Breech is the direct factory replacement, built to the same spec as the original so it seats and locks into the Firefly shell exactly as the stock part did.

If your Firefly's breech has cracked, chipped, or otherwise failed, swapping it out restores proper shell seating and lockup without needing to send the whole blaster in for repair. It's available in Yellow, Bright Orange, and Classic Orange, in addition to the standard finish, so you can colour-match or refresh the look of your build at the same time.
