M231 Firing Port Weapon

Produced by M231

The M231 Firing Port Weapon (FPW) is an adapted version of the M16 assault rifle for shooting from firing ports on the M2 Bradley. The M16, standard infantry weapon of the time, was too long for use in a "buttoned up" APC, so the FPW was developed to provide a suitable weapon for this role. Designed by the Rock Island Arsenal, the M231 FPW remains in service. All but the rear two firing ports on the Bradley have been removed.
