OTs-23 Drotik

It is designed as a special operations and personal defence weapon (PDW). It has compensator openings cut into the end of the barrel to vent gases and make the weapon more stable during automatic burst fire. The action is blowback complicated with a principle borrowed from Pedersen's hesitation locking: after passing 42 mm and ejecting the case the free-moving bolt locks with the barrel and uses its inertia to stop in the last 5 mm of recoil. Very few of these guns were manufactured; it was however the basis of the development of the OTs-33. The 5.45×18mm MPT cartridge, although successful in the PSM pistol, was considerably underpowered for a gun of this size and intended for PDW role.
