I classify "muzzle" as the final aperture through which the projectile passes before its major trajectory. In the case of the Maverick, the muzzle is separate from the chamber opening. In the Hammershot (and a limited number of other non-SSML blasters such as Firefly), the chamber opening and the muzzle are one and the same.

But that's just me. 😁
