Kovrov Mechanical Plant PKMT Tank Machine Gun

The PKT is a solenoid-fired coaxial version of PK to replace the SGMT Goryunov vehicle-mounted machine gun. Modifications include the removal of the stock, a longer and heavier barrel, a gas regulator and an electric solenoid trigger. The PKT is usually fed from 250-round ammunition boxes. The tank machine gun features a more heavy barrel that permits to deliver more intensive fire. Its gas-regulator operates on the principle of changing the cross-section of the gas-bleeder and not on the principle of gases exhaust as was the case with the PK and PKM machine guns in an effort to prevent extra gas pollution in the combat compartment of the tank. The PKMT does not have the sighting aids of its own, the operating handle and the stock, the appearance of the receiver is changed. The spring of the guiding tube of a piston rod removes the gap or the clearance between the tube and the receiver. The PKMT is equipped with an electric trigger mechanism. The tank machine gun is employed as the coaxial and the course weapon on the remotely controlled mounts. The PKMT was manufactured at the Kovrov Mechanical Plant and the Zlataust Machine-Building Plant.
