The Model 12 weighs 3.48 kilograms empty (about 3.820 kg loaded) and is 660 millimeters in length with stock extended (418 mm when retracted). Its short length is achieved by use of a barrel recessed into the bolt head, known as a telescoping bolt. This reduces length without reducing barrel length or bolt weight.[1] It fires from an open bolt and has a cyclic rate of fire of 550 shots per minute. Its muzzle velocity is 380 meters per second. It is accurate to 200/300 meters.
The barrel and rifling are chromium-plated to prevent fouling. The bolt housing has grooves to allow bolt movement, even in extremely adverse conditions such as exposure to mud, dust, or sand. The exterior surfaces of the firearm are finished with epoxy resin coating for protection against corrosion and damage.
The weapon has a selective-fire option allowing a choice of single shot or fully automatic fire.
The weapon has 3 safeties: a manual safety which blocks the trigger; an automatic safety on the rear grip which immobilizes the trigger and blocks the bolt in a closed position; and a safety on the cocking handle locking the bolt in case it does not retract.
The gun is equipped with a side folding stock, but is also seen rarely with a fixed stock.
20, 30, and 40-round box magazines were available for the original Model 12, which was chambered for the 9 mm Parabellum cartridge.
