History
The Swiss army, having carefully analyzed the combat use of the German single machine guns MG 34 and MG 42 , came to the need to introduce in the army the class of single machine guns of its own production. The competition for a new single machine gun was attended by MG 50 of the private company SIG and MG 51 produced by the state W + F. The latter was adopted [1] .
MG 51 was not exported. Present days [ when? ] its production is completed.
Description
Automation MG 51 is based on the recoil energy of the barrel with a short stroke. The design of the shutter and the locking assembly is similar to the MG 42, but instead of locking rollers, side-mounted combat stops are used . In addition, in the design of the Swiss machine gun was additionally mounted lever accelerator shutter shutter. With MG 42 copied the tape feed mechanism, the barrel quick change mechanism. The barrel casing is made of stamped steel sheet and is connected to the receiver by welding. The milled receiver is made of solid steel forgings [1] . The machine gun uses a metal non-loose tape with an open link [2] .
MG 51 can be mounted on a bipod or on a universal tripod machine and had a carrying strap and pad to mitigate the impact during recoil [1] .
The option for armored vehicles was produced under the index MG 73 [1] .
The main disadvantages of the machine gun are excessive weight and high cost of production due to high quality standards and the small number of copies produced [2] . On the other hand, an increase in the mass and accuracy of fitting parts increased the accuracy of fire [3] .
