| Lists on the subject | |
The Automatgevär m / 42 ( Ag m / 42 ) was a Swedish self-loading rifle . It was developed by Erik Eklund, the owner of Ljungman Pump AB in Malmö .
technology
The Ag m / 42 is a gas pressure loader with a tilting block lock. The gas pressure is fed directly to the bolt carrier via a gas duct. This has the advantage that fewer parts are required for the weapon to function, but above all the omission of the gas piston results in a steady position of the rifle after the shot has been fired and thus a higher hit density. Reliable reloading, however, requires ammunition specially tailored to the weapon; in particular, Schmauch can clog the gas duct. The bolt carrier slides on the bolt housing, the gas duct lies above the barrel.
After the last shot has been fired, the bolt carrier remains in the rear position. The trapezoidal magazine can only be exchanged with a little effort so that it can be cleaned. Charging strips are used for charging and are inserted from above through the open lock box.
The rifle is secured with a wing safety, which is attached behind the breechblock - similar to the Swedish Mauser rifle. Right position is secured, left unlocked.
The muzzle velocity of the 6.5 mm ammunition is 750 m / s.
commitment
In Sweden only about 30,000 were built, very few for a weapon in the structural equipment of an army. The standard rifle was still the Carl Gustaf M / 96 repeating rifle . From 1964 the Ag m / 42 was replaced by the modern AK 4 assault rifle, a version of the German G3 rifle . The Ag m / 42 turned out to be a very precise weapon, but it was quite long and above all heavy.
variants
m / 42B
With the m / 42B, minor disadvantages of the original model were corrected, for example it was given a stainless steel gas pipe, as it had been shown to be very susceptible to corrosion.
Egypt
After the Second World War, Sweden sold licenses and the manufacturing technology to Egypt, where this weapon was manufactured by the state Ordnance Factory, slightly modified as the Hakim 42/49 rifle, with the participation of Swedish technicians and engineers . The modifications included the conversion to the German cartridge 7.92 × 57 mm and the addition of a gas pressure regulator. Around 70,000 copies of the Hakim were built; with a curb weight of 4.71 kg, it was slightly heavier than the Ag m / 42. The remaining technical data are the same.
Also based on the Ag m / 42, the Raschid self-loading rifle was later created in the Soviet caliber 7.62 × 39 mm , of which only around 8,000 were produced. The barrel length was shortened by 122 mm to 500 mm, the total length of the weapon was reduced by 104 mm to 1016 mm, the empty weight sank to 3.90 kg. The projectile of the 7.62 × 39-mm ammunition reached a muzzle velocity of 735 m / s.
The Raschid was equipped with a bayonet that can be folded under the barrel, which corresponds to the bayonet of the Soviet self-loading carbine Simonov SKS-45 .
After the MPi Kalashnikov was introduced by the Egyptian armed forces, the production of the Hakim and Raschid rifles ended, but they remained in stock.
Denmark
Another license was granted to Denmark, but the weapon was not introduced there. only a few examples of the Ag m / 42 were made in Denmark.
