The M16 XM148 (M16A1 XM148) is a U.S. 5.56×45mm assault rifle fitted with the Colt XM148 40×46mm low-velocity underbarrel grenade launcher. It is best known as an early attempt to give M16 riflemen organic grenade-launching capability before the later standardization of the M203.

HISTORY

The M16 family originated from the AR-15 and was adopted for U.S. service in the 1960s as the military pursued lighter, small-caliber, high-velocity rifles alongside (and eventually in place of) 7.62×51mm battle rifles like the M14. Early Vietnam War service exposed serious reliability problems tied to ammunition changes, inadequate cleaning/maintenance support, and corrosion/extraction issues. These issues drove a set of engineering and training changes that were incorporated into the M16A1 pattern and supporting maintenance program, improving field reliability.

The XM148 was Colt’s early 40mm underbarrel grenade launcher developed for mounting on the M16 to supplement or replace the stand-alone M79 grenade launcher. It was ordered for field use in the mid-1960s and reached Vietnam, but the design proved overly complex and maintenance-sensitive in the field, with reports of durability and snag/handling issues. Because of these problems, the XM148 was withdrawn from widespread use relatively quickly and the concept matured into the simpler M203 pattern which became the long-running U.S. standard underbarrel launcher.
