MM Firefly Threaded Extended Barrel Set

If the standard Firefly barrel length isn't cutting it, the MM Firefly Threaded Extended Barrel Set trades that for extra length and extra capacity — this extended set lets your magazine tube hold a total of 6 shells instead of the standard count, which matters if you're running longer engagements or just don't want to reload as often.

Despite the added length, it keeps the same threaded design as the standard set, so switching barrels on your v2.5 Firefly stays quick and tool-light rather than turning into a strip-down job. It's available in Orange, Blue, and Pink, giving you a different colour spread than the standard set if you're after a specific look.

This is best suited to Firefly owners who've already got the threaded adapter sorted and want to go long rather than switch colours — pair it with the standard set if you want both options in your kit.
