The OTS-02 Kiparis (ОЦ-02 Кипарис, Russian for "cypress") is a Russian submachine gun first designed by the TsKIB SOO design bureau of Tula in the early 1970s, although it was not introduced into service until 1991.

[1] The receiver is made from pressed steel with a synthetic plastic pistol grip.

It feeds from stamped steel detachable straight box magazines, inserted into a well in front of the trigger guard with either a 20 or 30-round cartridge capacity.

The weapon has a rudimentary steel skeletonized stock which folds up and over the receiver when folded, in such a manner that the simple base plate outline extends downwards to either side of the muzzle.

The OTS-02 Kiparis can also accommodate a red dot sight or a tactical laser pointer which clips on forward of the magazine housing in such a way that the bottom of the laser aiming device can act as a forward grip during aiming.
