Armament 81 mm HE and WP smoke mortar bombs. Development By US Army Ordnance. Description The M716 is a super-quick delay arming impact fuze. The aluminium fuze head contains a spring-loaded striker and firing pin. A spring-loaded cylindrical slider, mounted transversely in the aluminium fuze body, contains the detonator and is equipped with an O-ring pressure seal. Inbore safety is provided by a spring-loaded bore riding pin that locks the slide. A pull wire restrains the setback pin (not shown in illustration)
which locks the bore riding pin. Tape and a plastic disc protect the metering orifice. The fuze base contains a booster lead charge and a booster charge. An adaptor assembly with two tetryl booster pellets and a cup with one pellet are threaded to the base.
