Jati-Matic

   The Jati-Matic submachine gun was designed in Finland by Jali Timari in the late 1970s and early 1980s. It is quite an unusual weapon, aimed at law enforcement forces and armored vehicle drivers. It's production commenced in 1983 and ceased in 1987. Only about 400 of these weapons were ever produced.

   The Jati-Matic is a blowback operated, selective fire submachine gun, chambered for 9 x 19 mm ammunition. The receiver is made from stamped steel. Many of the parts are made of plastic, while other are made of stainless steel and aluminum. This submachine gun has only 39 individual components.

   A unique feature of this weapon is that it's bolt recoils at inclined plane at an angle to the barrel. It gives an element of braking to the bolt and also resists the upward movement of the barrel during the fire. The pistol grip is located higher than on other SMGs. Recoil on this weapon is directed backwards, rather than upwards. It eliminates muzzle climb and makes the weapon more controllable. The Jati-Matic can be fired using only one hand.

   This submachine gun has got no buttstock, but comes with a folding forward grip. When opened, the forward grip also acts as a cocking handle. When folded, this grip acts as a safety element, as it blocks the bolt. This allows the weapon to be carried safely with a loaded chamber. The forward grip does not reciprocate during firing. The Jati-Matic is fired from the hip or extended arm position.

   Also there is no separate fire mode selector. Selection of firing mode is done with different trigger pulls of a two-stage trigger. A short pull produced single shots, while long pull results in fully automatic fire.

   The Jati-Matic is fed from 20- or 40-round magazines. It is also compatible with magazines of the Carl Gustav M/45 submachine gun. The Jati-Matic has fixed iron sights, set to 100 meters.
