The M231 Firing Port Weapon (FPW) is an adapted version of the M16 assault rifle for firing from ports on the M2/M3 Bradley AFV. The infantry’s normal M16s are 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 although all but the rear two firing ports on the Bradley have been removed.
