Design details.
The OTS-02 is a blowback-operated weapon of a conventional design chambered in 9×18mm Makarov.
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 Kiparis is supplied with a proprietary sound suppressor with a service life of approximately 6,000 rounds, the same service life as the barrel.
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.
