A 12-gauge shotgun, nominally 18.5 mm (0.73 in), can range from a tight 18 mm (0.71 in) to an extreme overbore of 20 mm (0.79 in). Some also claim an increased velocity with the overbored barrels, up to 15 m/s (49 ft/s), which is due to the larger swept volume of the overbored barrel.

A few Mark 38 machine gun systems use the Mark 96 Mod 0 machine gun mounting. This MGM features both an M242 Bushmaster and a 40 mm Mark 19 grenade launcher. It also has stabilization—it automatically moves to compensate for pitch and roll of the ship. However, like on Mk 38 Mods 0 and 1, this mounting required someone to physically operate. [3]
Its intended use is in an air defense or direct-fire role, mounted on either naval or land platforms, replacing existing 20 mm cannon where applicable. The Model 811 has been installed on the Nexter Vextra 8 × 8 technology demonstrator for trial purposes.
