The PZD 556 light machine gun is a fully automatic weapon that provides crucial fire support for team or operator. It is carried and operated by single operator, and when needed can be mounted in mil-spec cradles and perform a limited range of tasks as a universal machine gun. The weapon fires from an open bolt, the breech is locked by the rotating bolt and unlocked by a screw slide, which is carried to the rear by the action of the piston carrier which is pushed by the propellant gases.

Calibration is an essential process that verifies the compliance of a measuring instrument with its design and functional specifications. By conducting calibration, we can determine the deviation value of the measuring instrument and ensure that it aligns with its specifications. As time progresses, the performance of a measuring instrument inevitably declines, and it becomes necessary to calibrate it to preserve its function and performance. The advantages of calibrating a measuring instrument include preserving its function and performance, preventing product defects, maintaining the instrument’s condition to align with its specifications, avoiding hazardous risks, and minimizing work accidents to ensure workplace safety.
