The Sa vz. 58 is a 7.62 mm assault rifle designed and manufactured in Czechoslovakia, accepted into service as the 7,62 mm samopal vzor 58 (“7.62 mm automatic firearm model 1958”), replacing the 7.62 mm vz. 52 self-loading rifle and the 7.62 mm Sa 24 and Sa 26 submachine guns.

Development of the weapon began in 1956, and leading the project was chief engineer Jiøí Èermák at the Konštrukta facility in Brno. The rifle was designed to use the Soviet intermediate 7.62x39mm M43 cartridge, rather than the Czech 7.62x45mm vz. 52 round, used in both the earlier vz. 52 rifle and the vz. 52 light machine gun. Over the period of 25 years (up until 1984) over 920,000 had been produced, used by the armed forces of the Czech and Slovak Republics, Cuba and several other Asian and African nations.

The vz. 58 was produced in three main variants: the vz. 58 P (Pìchotní - \"infantry\") – with a fixed buttstock, made of a synthetic material (wood impregnated plastic, older versions used a wooden stock), the vz. 58 V (Výsadkový - \"airborne\") – featuring a metal wire stock, folded to the right side, and the vz. 58 Pi (Pìchotní s infraèerveným zamìøovaèem - \"infantry with infrared sight\"), which is similar to the vz. 58 P but includes a receiver-mounted side rail (on the left side of the receiver housing) used to attach an NSP-2 night vision sight; it also has a detachable folding bipod
