Czechoslovak rifle self-loading type ZH-29
At the end of 20's, designer E. Holek worked on the creation of a self-loading rifle at the Czechoslovak Ceska Zbroevka plant. It is named after the first letters of the plant and the name of the designer ZH-29. For the first time, rifles began to be produced in the 1929 year.
This weapon It was developed specifically for ammunition 7.92x57 Mauser for the main customer - China. The serial production of the rifle was adjusted to the 1939 year. There were attempts to use a rifle for different types of ammunition from different countries, but no orders for a rifle were received from anyone. During the occupation of Czechoslovakia by German troops, the release of weapons was stopped.
The main reasons why the rifle was not widely used - is the difficulty of manufacture and the high price of one instance compared to other similar rifles. In addition, the rifle was sensitive to contamination and unreliable when used in unusual conditions.
The rifle uses automation with a gas outlet into the cylinder located under the barrel. The barrel is locked by the lateral bias of the shutter, for the notch of the trunk box. In addition to the self-loading type, the ZH-29 automatic rifles were also produced at the Czechoslovak plant, which could fire in small bursts. The ammunition was supplied from detachable box-type stores with various capacities. Shops could be recharged from the clips when the rifle bolt was in the open position. The rifle mechanism had a slide lag, which stopped the bolt when the cartridges were used up from the magazine, in the open state. The removal of this state was carried out by pressing the hook, the next pressing on which led to the production of a shot.
The peculiarity of the Czechoslovak rifle is the presence of a ribbed aluminum radiator, which is located on the gun barrel in front of the forearm. The rifle was made open adjustable sight and tide to install the bayonet.
