The VZ.52 is a Czechoslovakian Light Machine Gun, developed after the end of the Second World War. It was designed to be used by the Czechoslovak Armed Forces in the 1950's
The VZ.52's internal mechanics are largely based on the earlier ZB.26 (designed by Vaclav Holek) which utilises the same gas operating system and interchangeable barrel system. However it also utilises a tilt bolt that locks to the roof of the reciever, aswell as an integral bipod and the ability to use either a box magazine or a metallic belt, without to need for modifications.
Initially the VZ.52 used Czech 7.62mm x 45mm vz.52 cartridge. The gun was modified to use the 7.62mm x 39mm Warsaw Pact round and redistributed as the VZ.52/57.
Both the VZ.52 and the later VZ.52/57 were used by the Czechoslovakian Army, until 1963/4 when they were replaced by the Universal Machine Gun Model or Uk vz.59.
