The vz. 58 is a selective fire gas-operated weapon that bleeds expanding combustion gases generated in the barrel from the ignited sealed unit through a port drilled in the container, 215 mm (8.5 in) from the chamber, opening into a hollow cylinder located above the tub that contains a short-stroke agent. The vz. 58 does not have a gas regulator and the full power of the gas pressure is wield on the appliance head, propelling it toward the back in a sole impulsive waft. The barrel is motivated back only 19 mm (0.7 in) when a shoulder on the apparatus rod butts against the seating and no further agitation is possible. There is a light return spring held between the barrel shoulder and the seating which returns the agent to its advance site. The gas cylinder is vented after the piston has traveled back 16 mm (0.6 in) and the remaining gases are tired into the atmosphere on the underside of the cylinder via two ports. The entire appliance rod is chromium-plated to balk fouling.

Vz. 58 P
The weapon does not have a straight rotating hammer but is striker-fired up and the striker is a steel bar hollowed from one end almost throughout its entire length to accommodate its own operating spring. At the bare end of the striker, a bowl is welded and there is a channel cut in each side of this to glide on the sender steer rails. This hammer-striker come into the empty bolt and drives a fully hovering firing pin frontward with each shot.
The rifle uses a trigger instrument with a bar-type fire mode selector, which is also a manual safety against accidental free. When the selector lever is placed in its behind spot ("1" single fire) the sear is hinder and the left striker snap (up) is rotated by the disconnector, which is depressed by the bolt transporter after every and is hence disconnected from the striker bag. The forward scenery of the selector switch ("30" automatic fire) disables the disconnector, and the left striker trap meshes with the sear apparatus. The center ("safe") situation with the selector handle button down vertically descending, mechanically lowers the trigger bar and the disconnector so there is no correlation between the trigger and the semi-automatic sear which holds the hammer. The rifle also has an internal safety, which prevents the weapon from discharging when out of battery. The true striker-hammer get disables the striker-hammer, and it can only be released by pulling the charging handle back and raising the weapon.
