MG 42/59 or 7,62 MG3 milimeter Steyr Daimler Puch di Vienna
When 42 MG comrade for the cartridge from 7,92 x57 milimeter Mauser made its income on the battlefields of the second world war, this automatic weapon rivoluzion˛ the design of the machine-guns not only for its rimarchevoli mechanical solutions, but also for its construction that previewed a great number of parts in printed publication sheet allowing one faster and economic production of the arm.

Beyond to a series of solutions and sagacities already happening to you experiments with on other crews as the system of fast substitution of the cane, version improved of that one used on the Italian machine-gun Breda, MG 42 offered to other interesting technical characteristics a lot which, as an example, a mechanism of feeding of remarkable functionality, than it was later on demonstrated therefore perfect to be adopted on other machine-guns like the American M60. It seems however that the system of closing to seams of MG 42 is derived from a Polish prototype, put to point from Edward Stecke before the conflict and fallen in hand to the Germans in 1939.
During the second world war MG 42 was produced in varied migliaia of exemplary from numerous companies of 3░ the Reich which the Mauserwerke of Berlin, the Steyr Daimler Puch di Vienna, the Waffenfabrik di Suhl and the Johannus Grossfuss Mettal und Locierwaffenfabrick di Doblen. For the report we remember that industrialization of MG 42 was cured from a dependent of this last company, Grunovv engineer to which the semplicitÓ of fabrication of this exceptional arm must of the rest.
In the post-war period the production of an modernized version of MG 42 was undertaken from the Rheinmetall di Dusseldorf on behalf of the German Armed Forces. The arm was comrade for the employment of the cartridge from 7,62 x 51 milimeter and offer commercially like MG 42/59. To notice however that the first post-war MG, said also MG 1 in the German military nomenclature, were employed from the guards of border of the federal Republic in bore 7,92 milimeter Mauser.

Evolution and varying of MG 42/59
From the date of its putting in service in the Bundeswehr like MG 1, the arm has endured some small and successive modifications based on which assume various denominations:
- MG 1A1: draft substantially of one MG 42/59 of the first series converted to bore 7,62 x 51 milimeter by means of the adoption of one new chromium plated cane, organs of sight with calibration modified for the new type of supply and a suddenly leggermente various device.
- MG 1A2: characterized from the castle of new conception, the window of increased expulsion and the shorter throttle of armament. On this version, that it can use recoverable fixed metallic tapes or those to disintegrabili sweaters type US M 13, it is possible to mount a heavier stopper that concurs than to reduce the cadence of shooting they give beyond 1.200 to approximately 800 blows to the minute. E' this version that has been adopted and produced on licence in Italy.
- MG 1A3, practically similar to the MG 1A1 as far as the group cane, but with small modifications to the stopper, the mechanism of feeding and the device suddenly that it has been reinforced.
Parachutist with MG 42/59 Beyond 200.000 exemplary of varying MG 42/59 in its several they have been produced up to now in Germany, where currently the disseminated version more is MG 3, last of the series that differs from the previous versions for some details between which the added one of I raise for the shooting antiaircraft, the shape of the flame damper and the adaptability of the system of feeding to whichever type of tape (fixed and recoverable type DM 1, to disintegrabili sweaters type DM 6 and US M 13).
MG 3 can be employed is with bifoot like accompanyment arm, than with treppiede like medium machine-gun of support, installed on vehicles like single arm of edge or coaxial arm (MG ┴1), beyond that to be equipped of devices of tracking for the shooting diurnal or nocturnal. It goes specified that on it puts into effect them versions of MG 42/59 can be mounts two various types to you of stoppers and shocks-absorber: the V550 stopper, than hung exactly 550 grams, with the relative shock-absorber N type (cadence of shooting from 1.100 to 1.300 blows to the minute); the V950 stopper, heavy 950 grams, with its shock-absorber R type (cadence of shooting from 700 to 900 blows to the minute).
Beyond that from the Bundeswehr, MG 42/59 has been adopted from the Armed Forces of numerous Countries of all the world, the arm has been manufactured on licence also in Italy from the Beretta and the Luigi Franchi, in Spain from the CETME, Portugal from the INDEP, Pakistan from Pakistan Orcinance Factories, in Turkey from the MKE and the former Yugoslavia from the ZCZ, where the model produced from the arsenals of Kragujevac in Serbia, famous like Sarac M 53, is camerato for the ammunition 7,92 bore milimeter Mauser. To notice that MG 42 originates still it is used them in several places of the world.

Operation and employment
Cooled machine-gun to working air and short recoil of the cane with geometric closing to seams, MG 42/59 shoots to open stopper waves to only avoid problems of cock-off (pre-ingition of one cartridge in one overheated room) and in automatic modality (free squall). If the arm comes used mounted on bifoot the practical throw of employment is of 400-500 meters, while if mounted on treppiede this varied throw from 800 to 1.000 meters. To notice that I raise it place in front of the cover of the castle it is graded from 200 to 2.200 meters.

The load of the arm happens by means of the introduction of the tape in the feeding slit (left side) or more simply opening the cover of the castle and supporting the first cartridges of the Particular one of you break off flame and of I raise collapsible mounts to you on MG 42/59 tape directly on the feeding slab (to assess in any case that the first cartridge goes to lean against the detention peg place on the feeding slab). Withdrawing to the maximum the armament throttle the stopper remains open and the arm is ready to the fire. A sure handbook to push-button it is placed on the skillful flank of the arm, exactly over the gun grip (the sure one disinserisce pressing the same push-button from left towards right). In order to unload the arm it is necessary to withdraw the armament throttle completely and to insert the sure one: to raise therefore the cover of the castle and to remove the tape. He is not advisable to leave to return the stopper in closing to empty room. And preferibile to complete this operation saldamente withholding the armament throttle while the trigger is pressed so as to to bring back the stopper in position advanced with a movement it graduates them. It goes emphasized that on the window of expulsion and place a motivating force cover whose opening happens automatically pressing the trigger: when the arm does not come used is advisable to close this cover in order to avoid that bodies strangers or soil penetrate in the mechanism of the arm.
The taking apart on the field of MG 42/59 is extremely simple and works allowing them one fast and easy ordinary maintenance of the arm. In order to take apart the cane it is first of all necessary to arm the stopper. One then pushes to the infuori the handle of taking apart on the right, operation that allows to extract the extremity of the cane outside from its center and concurs of toglieria from the posterior part. Once raised the cover of the castle, removes the locking pin and the feeding system is separated from the arm. After it are assures to you that the stopper is advanced, removes the calciolo same, while with the free hand it is made to ruotare of 1/4 of turn to right or on the left. Fact this, can be extracted the ammortizzatrice motivating force of recovery pressing the containment that is situated to the posterior extremity of the castle. The trigger is pressed finally pulling with the other hand the throttle of the armament undercarriage so as to to carry the stopper on the posterior opening of the castle from where it can be extracted. Ulterior taking aparts are of the all useless for one normal maintenance of the arm.
Arm extremely very conceived, sturdy and reliable also in the most adverse conditions of employment, MG 42/59 is destined to still remain in service in order much time.
