One of the interesting armourer jobs I got while recovering from a badly-infected small arms hit to my lower back was grinding the bayonet lugs off some 200 early M16 rifles being handed over to our Vietnamese ARVN allies as American forces were getting M16A1s. The rifles were to be fitted with XM148 40mm grenade launchers, and it seems that during the Tet '68 fighting, one earlier ARVN grenadier fired off his XM148 with the bayonet locked in place on his rifle.
Ooops.
