While externally the vz. 58 resembles the Soviet AK-47, it is a different design based on a short-stroke gas piston. It shares no parts with Kalashnikov rifles, including the magazine.
History
This section needs to be updated.(December 2023) |
Development of the weapon began in 1956; leading the project was chief engineer Jiří Čermák assigned to the
The vz. 58 was produced in three main variants: the standard vz. 58 P (Pěchotní or "infantry") model with a fixed buttstock made of a synthetic material (plastic impregnated wood, older versions used a wooden stock), the vz. 58 V (Výsadkový—"airborne"), featuring a side-folding metal shoulder stock, folded to the right side, and the vz. 58 Pi (Pěchotní s infračerveným zaměřovačem—"infantry with infrared sight"), which is similar to the vz. 58 P but includes a receiver-mounted dovetail rail bracket (installed on the left side of the receiver) used to attach an NSP2 night sight; it also has a detachable folding bipod and an enlarged conical flash suppressor. For the first two variants, the two types of stock are interchangeable and mount to the same mounting point on the rifle itself, which is identical in either variant.
A successor to the vz. 58 was proposed in the 1990s; the

Operating mechanism
The vz. 58 is a selective fire gas-operated weapon that bleeds expanding combustion gases generated in the barrel from the ignited cartridge through a port drilled in the barrel, 215 mm (8.5 in) from the chamber, opening into a hollow cylinder located above the barrel that contains a short-stroke piston. The vz. 58 does not have a gas regulator and the full force of the gas pressure is exerted on the piston head, propelling it backwards in a single impulsive blow. The piston is driven back only 19 mm (0.7 in) when a shoulder on the piston rod butts against the seating and no further movement is possible. There is a light return spring held between the piston shoulder and the seating which returns the piston to its forward position. The gas cylinder is vented after the piston has traveled back 16 mm (0.6 in) and the remaining gases are exhausted into the atmosphere on the underside of the cylinder via two ports. The entire piston rod is chromium-plated to prevent fouling.
The locking system features a locking piece hinged from the bolt and housed in the bolt carrier that contains two locking lugs which descend into and engage locking shoulders in the receiver's internal guide rails. The weapon is unlocked by the short tappet-like stroke of the piston rod as it strikes the bolt carrier and drives it rearwards. After 22 mm (0.9 in) of unrestricted travel, a wedge-like surface on the bolt carrier moves under the hinged breech locking piece and lifts it up and out of engagement with the locking recesses in the steel body. The hinged breech locking piece swings up and this movement provides the leverage required for primary extraction. The breech block is then carried rearwards extracting the empty cartridge casing from the chamber. A fixed ejector passes through a groove cut in the underside of the bolt and the case is flung upwards clear of the gun.
Features
The spring-loaded extractor and firing pin are both housed inside the bolt, while the fixed ejector is slotted inside the receiver. The extractor retains the firing pin and is powered by its own plunger and spring.
The weapon does not have a conventional rotating hammer but a linear hammer instead. The hammer is a steel cylinder hollowed from one end almost throughout its entire length to accommodate its own operating spring. At the open end of the cylinder, a plate is welded and a groove is cut in each side of this to slide on the receiver guide rails. This linear hammer enters the hollow bolt and drives a free-floating firing pin forward with each shot.[7]
The vz.58 uses a trigger mechanism with a lever-type fire mode selector, which is also a manual safety against accidental discharge. When the selector lever is placed in its rear position ("1"—single fire) the sear is disabled and the left hammer catch is rotated by the disconnector, which is depressed by the bolt carrier after every shot and is therefore disconnected from the hammer catch. The forward setting of the selector lever ("30"—automatic fire) disables the disconnector, and the left hammer catch meshes with the sear mechanism. The center ("safe") setting with the selector lever pointing vertically downwards, mechanically lowers the trigger bar and the disconnector so there is no connection 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 right linear hammer catch disables it, and it can only be released by pulling the charging handle back and cocking the weapon.
The weapon is fed from a detachable
An interesting feature on this rifle is the ability to quickly change the type of stock. The vz. 58 can appear either with its original fixed stock (in either beech wood or composite material) or folding steel stock, or with one of the many aftermarket stocks available – including AR-15 style stock adapters that mount a buffer tube to the receiver. The latter usually has the buffer tube slightly angled down as to compensate for the very low ironsights on the vz. 58. Switching between the various options requires merely removal of a bolt at the rear of the receiver and swapping in the stock of choice.

Accessories
Several modernization accessories have been manufactured for the vz. 58 platform from different companies. Accessories include "tactical" bolt release, extended and/or ambidextrous magazine release paddles, ambidextrous fire mode selectors, custom handguard rails, several types of sight mounting options and various muzzle brakes and compensators. Both civilian and military users use these upgrades, and they also see frequent use with private military companies in the Middle East.
Additional equipment supplied with the rifle includes: 4 spare magazines, a magazine pouch (in either canvas, leather, or leatherette), vz. 58 bayonet and scabbard, cleaning brush and rod, muzzle cap, oil bottle, unified sling, front sight adjustment tool, disassembly aid and a threaded
