Cutting weapons down for lightness and ease of carry was a trademark of the Special Forces in Vietnam, particularly for their "Over the Fence" missions into Laos and Cambodia. One member famously carried a cut down M60 for fire superiority when required, another, a helicopter pilot for clandestine insertions carried a cut down M2 Carbine to hose down anyone charging his chopper and John "Tilt" Meyer of RT Idaho fame turned an M79 grenade launcher into a handgun.
