VZ-58 Assault Rifle

The PUSKA VZ58 (Rifle Model 1958), is available in 2 models (the P model, with fixed buttstock, and the V model, with folding buttstock) were used by the Czechoslovakian Army since their agreement with the Warvz58 Pact. It is one of the VERY FEW "original" assault rifles used in the Warsaw Pact's countries (since most of those adopted the russian made AK47, then starting production of national-made AK copies). While this rifle can be similar to the AK in external appearance, the VZ58 utilizes a completely different locking principle. It is currently in service with Czech and Slovakian armies.

The Samopal vzor 1958 (submachine gun, model of 1958) was the standard assault rifle of the Czechoslovak army from the late 1950s and until the dissolution of the CSSR in the 1993. At the present time the SA Vz.58 is still used by the Czech and Slovak armies, as well as sold for export in some quantities. The SA Vz.58 vz58 not much of real combat, so it is hard to judge how it stakes up against the most known contemporary rivals, like the Soviet / Russian AK-47 or the US M16A1. But the overall quality, fit and finish of this rifle is excellent. This rifle had been designed by the Czech arms designer Jirí Cermák, under the project codename "KOŠTE", or "Broom", in English.

The SA Vz.58 is a gas operated, magazine fed, selective fire weapon. It uses more or less conventional short stroke gas piston, located above the barrel. The gas piston has its own return spring. The locking system features a linearly moving bolt (breechblock) with a separate tilting locking piece. The breechblock (bolt) is located under the bolt carrier, and the locking piece is hinged to the bolt and located under it. Gun fires from the closed bolt all times. When gun is fired, the gas piston gives a short tap to the bolt carrier. After a free movement of about 22 mm (.9 inch) the bolt carrier swings the locking piece up from the locking recesses in the receiver, and thus unlocks the bolt. From this moment on the bolt group moves back at once, extracting and ejecting the spent case and chambering the fresh cartridge. At the end of the return stroke the bolt stops in the forwardmost position against the breech face, while the bolt carrier continues to move forward, swinging the locking piece down and into the locking recesses, thus locking the bolt to the receiver. The overall system can be roughly described as a mix between the Walther P-38 pistol and the Czech ZB-26 (or British Bren) machine gun locking. The charging handle is attached to the right side of the bolt carrier.

The trigger / hammer unit also differs from the most common designs in that it is a striker fired design. The massive cylindrical striker is located at the rear, hollowed part of the bolt, and has its own spring located under the bolt group return spring. The striker has a lug that interacts with the sear and is used to hold the striker in the cocked position. The overall design of the trigger unit is relatively simple and has few moving parts. The safety / fire mode selector switch is located at the right side of the receiver, and has 3 positions for safe, single shots and full automatic fire.

The basic variant, SA Vz.58P, has a fixed buttstock, and furniture made either from wood (early models) or from wood-impregnated plastic (late production models). The SA Vz.58V has a side-folding metallic buttstock, and the SA Vz.58Pi is similar to the SA Vz.58P except that it has a large mounting bracket on the left side of the receiver, that allows for the IR / Night sights to be mounted.

The sights are of open type, with hooded front post and open notch adjustable rear.
