Part 1: One of the production method used in producing most of the riffle part is through KB-P-580, which serves to be more reliable than most of the other production method and way more better handling characteristics, this method was used in 1948 in Izhevsk factory. Its banana shaped magazine or cartridge is manufactured through curve which is smoothly fed with ammunition, the steel used is quite heavy mixed together with feed-lips which makes it highly resistant to damage in the long run. The design of the magazine is borrowed from other guns and was used in AS-44 model by the soviets.
The receiver which anchors the integrated gas piston and the trigger is made of sheet metal with milled trunnion insert. In the year 1940, it took about 150 totally different machine motions to make it.so the new method of making it has differently changed it and help reduce the weight of the gun to only 8 pounds. The gas piston and bolt carrier contained in the receiver were deliberately structured to fit loosely in the receiver and the aim for this is to stop carbon buildup, dust and rust. What should be noted here is that this method of loose fit was borrowed from other designers like Sudayev and the concept was used by several other people after his death.
The stock of the AK-47 rifle is made of wood. There have been a lot of developments when it comes to the making of this particular type of gun and some of its features being borrowed from other gun designs. Guns which have folding stocks are better fitted for tighter spaces for instance airborne troops.
A combination of the bolt carrier and gas piston make up the gas piston which is a design that is not original but borrowed from another gun. The design is made to provide more energy to the operating system of the gun. How it works is that, when each round is fired, there is a gas which enters into a chamber through a port in the top of the barrel which in turn drives back a piston that then withdraws the bolt from the chamber and removes the already used cartridge. The magazine contains a spring which pushes the next cartridge into its place. There is a return spring which pushes the piston and bolt in front placing the cartridge in its chamber in readiness to fire once again. This system is much better since its stroke is 50% longer than usual which makes the gun versatile and still performs even when infiltrated by foreign substances like water which impedes lubrication. The protective coating of the gun is a phosphate coating which increases its reliability when it comes to rusting. The chamber and barrel of the gun are actually chromed which also helps fight rusting. These anti-corrosive features of the gun are very key when it comes to harsh climate conditions like in times of war. Compared to other guns like an M16 before their chambers and barrel were chromed and which there protective coating were vulnerable to corrosion, AK-47 stood out in this aspect. The selectors switch which regulates when the gun can fire and when it cannot. The options of the switch are; safe, semi-automatic and automatic. When the gun is in the safe mode it is not able to fire. When it is the semi-automatic the shots are single shot and finally the automatic mode which fires rounds in a continuous mode when the trigger is pulled. Finally the trigger of the gun is a borrowed design from the M1 design created by John c and a German gun maker called Schmeisser who was in prison at the time the legendary AK47 rifle was made. Part 2: One production method I would use to produce the riffle is Izhmash production method which produces around 95 units per hour which is an equal amount of over 1 million units per year. The fact that while using this method most parts are joined using hands, makes it more effective and accurate increasing
