The main Gun Housing provides mounting surfaces for the Drive Motor, Safing Top Cover, Feeder/Delinker, and Spade Grips. Additionally, the Gun Housing contains the Rotor and Clutch.
Located on the rear of the Gun Housing are four Spade Grip Mounting lugs. The lugs provide a firm-mounting surface for the Spade Grips. This differs from older methods of mounting Spade Grips to the Clutch Housing, which tended to shift as the gunner moved the weapon.
Dillon makes two types of housing. The Standard M134D housing is made from steel. The M134D-T utilizes titanium to reduce weight. Part life for the steel gun housing is one million (1,000,000) rounds and for the titanium gun housing is three hundred thousand (300,000) rounds. After this limit has been reached the housing is considered "serviceable on condition". This simply means that as long as the housing checks within tolerance it may continue service.
