    Development manual automatic weapons under the intermediate cartridge was launched in Germany in the mid-1930s and intensified with the entry of Germany into the war against the Soviet Union in 1941.

    as the base for a new arms ammunition was chosen intermediate cartridge caliber 7.92x33 (7.92mm Kurz), developed by the German company proactively Polte.

    April 18, 1938 Research Bureau of the 2nd Division for testing and designing hardware HWaA concluded with the owner of the weapons company Zulian C. G. Haenel, known gunsmith Hugo Schmeisser, a contract to develop automatic rifle.

    new rifle received the official name Mkb (Maschinenkarabin - automatic carbine) differ from those of MR (Maschinenpistole - sub-machine gun).

    design teams on designing Mkb himself headed X. Schmeisser. In early 1940, he transferred to the custody HWaA first prototype automatic rifle under the "short" Insert Company "Polten».

    Since late 1940 to fight for plum joined another of the most famous German arms companies - "Walter» (Walther) under the leadership of Erich Walter, who managed to obtain a contract for his company in HWaA for research program Mkb. He proposed the creation of a weapons system under the same conditions as C. G. Haenel, but using the waste sector is already fully shop from Mkb system Schmeisser dual inline thirty rounds.

    Firm "Walter" started to work in the firm belief that under her power production better weapons than the competition, due to a strong industrial base and higher research and design potential, historically developed over many decades of work. < / p>

    Mkb Walther, largely repeating the previous design firm started in the thirties, but had a lot of innovations.

    vapor system powder gases is removed from the bore into the housing through the two holes used for moving of the annular piston located around the barrel and bushing. However translational movement shutter piston is not carried out as in the previous samples and the sleeve. The barrel is locked by turning the bolt also. Lugs shutter located in front of him. Translator type of fire - both sides, lever type.

    Sights, raised for the convenience of shooting consisted of flies with namushnike and sectoral sight at 800 meters, mounted on high ground.

    For better stability under continuous fire moving parts automation and applied along the same axis with the barrel.

    Virtually all

    carbine going from stamped parts.

    Forearm - metal, rolled out of sheet steel.

    butt is made of wood.

    In deadlines made the first prototype, and in early 1941 the company "Walter" presented his officers of artillery and logistics HWaA. Although rifle and showed satisfactory performance in shooting of the landfill in Kummersdorf, work on finishing this still imperfect structure continued throughout 1941.

    In late January 1942 for extensive competitive testing HWaA demanded firm C. G. Haenel increase the initial order to manufacture Mkb in 1942 to 200 units, and from the company Walther to July 1942 were required to submit 200 automatic rifles of its construction. Both systems HWaA assigned name Mkb. 42, the article C. G. Haenel with index «H» - Mkb. 42 (H) of the company and machine Walther, respectively «W» - Mkb. 42 (W).

    After demonstrating prototypes Mkb. 42 (W) and Mkb. 42 (H) on the official show in July of the same year, the German Ministry of guide arms and HWaA remained in the firm belief that both companies will soon finalize its products and the end of summer they can be run in production. Moreover, it was assumed that the firm by November will produce 500 Mkb, and by March next year, the total production will be able to bring up to 15 thousand per month.

    But those plans went awry. In August 1942, after tests Mkb. 42 (W) and Mkb. 42 (H) control HWaA introduced new requirements in the original specifications. Generalization of experience fighting on the Eastern Front, and in Africa showed that a promising model of primary weapons infantryman must be multifunctional, that is not only striking fire, but (melee) bayonet and butt. In view of the installation at standard carbines "Mauser" 98k rifle grenade, and it was decided to have Mkb similar devices. Firms were instructed to mount on tree automatic carbines tide bayonet and to provide the possibility of mounting a rifle grenade nadkalibernogo model 1940. Amendments briefly, but slow transfer Mkb. 42 production. At the same time, the problems encountered in C. G. Haenel with subcontractors, while Walther with the establishment press-stamping equipment, led to the fact that by October of each firm ordered Mkb none was made.

    Mkb. 42 (H) - top
    Mkb. 42 (W) - Lower In November

    firm Walther, with monthly production rate of 500 units, supplied only 25 Mkb. 42 (W), and in December - 91 apiece. Thanks to the support of the Ministry of weapons, both firms to the top in 1943 were able to resolve the most serious production problems. So, from 500 Mkb, slated for production in January of that year, was nedopostavleno only 200 pieces, and in February and C. Walther G. Haenel actually exceeded the level of production to obtain a 1217 carbines plan together thousands of pieces. Minister of Armaments "Third Reich" Alfred Speer, in order to more fully explore the service and performance Mkb. 42 (H) and Mkb. 42 (W), orders the fact that a number of rifles were sent to undergo military trials on the Eastern Front.

    Both automatic carbine

    due to stiffness specifications HWaA, and also because of the widespread use of stamping and welding technology, had a very constructive between similarity. Tests revealed that although Mkb. 42 (W) and was lighter, more compact and better balanced, which largely affected the effectiveness of fire, yet there was no doubt that his complicated automation is not suitable for use in harsh field conditions. Mkb. 42 (H) proved to be simpler and more reliable its competitor. The results of tests of new weapons, HWaA decided to give preference to design Schmeisser, but only after making some modifications carried out in the future under the ciphers MP 43 / MP 44 / Stg.44.

    This development

    MKb-42 (W) has been completed.

    In the 1942-1943 period has been released, according to various sources, about 3 thousand machines Mkb. 42 (W), directed to the existing part of the Wehrmacht on the Eastern Front.
