It is often said that the Stern submachine gun during World War II only cost 9 dollars because of its minimalist design. It is estimated that many people have doubts about the price of weapons during World War II. Since submachine guns that can shoot automatically cost only $9, what is the price of rifles? Dog, this article casually talks about the cost of submachine guns and rifles.

Stenden is indeed the cheapest submachine gun during World War II, but according to English information, its cost is actually 10 ... Well, there is not much difference between 9 and 10. According to the inflation rate, it is about 140. Another very cheap submachine gun is the M3 grease gun of the American imperialists, which cost about $ 15 in that year, and after inflation, it was about $2 15 in modern times. And what was the price of the rifle at that time?

Kar 98 k: 28 dollars

M 1 Garland: 3 1 USD

Li En Field: $25.

Then the question is, why is a rifle more expensive than a submachine gun? Especially the bolt-moving rifles are more expensive than submachine guns, and the repeating ones are more complicated than Kamijozu's?

Yes, in terms of structure and materials, rifles are more expensive than submachine guns.

First of all, the kinetic energy produced by a pistol bullet fired by a submachine gun is often only about one sixth of that of a rifle bullet. According to Newton's third law, the reverse force exerted by a submachine gun bullet on the bolt is also only one sixth of that of a rifle bullet. This gives the submachine gun a prerequisite for automatic shooting-a simple free gun can be used to realize inertial locking.

However, the rifle can withstand the powerful reaction force of the rifle bullet by using the rotary bolt locking. This is not to say that the free bolt machine cannot be used, but that if the rifle bullet uses this principle, the bolt machine must be very heavy, otherwise it will unlock the lock in advance, resulting in the shell casing and gunpowder gas directly pasting the chamber and then spraying the hand's face. However, the rotary bolt locking has to have a nose with a locking tenon and a joint sleeve to clamp the tenon. The structure is more complicated than the free bolt machine, and the cost naturally goes up.

Moreover, because the free bolt is under pressure by that bolt, there is almost no pressure on the submachine gun case, so we can see that most submachine guns used punch boxes during World War II. Although the stamping equipment is expensive, it is very cost-effective in terms of time and cost when mass production. On the other hand, when the rifle is locked, it has to be placed on the case or joint sleeve. These pressure-bearing parts have to be milled, and the strength of stamping can't be hold completely, and the cost of milling is much higher than that of stamping.

And the barrel, submachine guns are close combat weapons, and there is no need for such a long barrel at all. The barrel is one of the most expensive parts of a gun. For example, Stern's barrel is only 20cm, while Li En Field is 64cm, which is the gap. There are only two rifling in Stern barrel and five rifling in Li En Field. Although many rifling were generally pulled out at one time by multi-point pin pulling method, the less the number of rifling, the less the pulling resistance and the faster the processing. Submachine guns can also save a lot of money on the barrel.

There are other things that can be seen at a glance, such as the wooden body and stock of rifles. Stenden only has stamped parts and welded parts, and even the stock is so insincere. At that time, the door of the submachine gun was a simple gap or hole, and the rifle had to have a set of gauges. The accuracy of submachine guns is not so important, and the factors that affect the accuracy, such as trigger force and barrel details, are not too particular when accepting, but the acceptance accuracy of rifles is much stricter than that of submachine guns.

Finally, by the way, talking about pistols, the cost of m191in World War II was 15 dollars, just like the M3 grease gun. Although it is small and saves materials, its structure is actually more complicated than M3. Because of the size limitation of the pistol, it is impossible to install a large and heavy free bolt (sleeve) like a submachine gun. Therefore, for the .45 ACP and 9mm pistol, the principle of short recoil of rigid locking barrel is needed, which is much more complicated than the free bolt. Moreover, the pistol is small in size and does not have as much space redundancy as the submachine gun, so the processing of parts is more detailed than the submachine gun, so it is slightly more expensive than the submachine gun. Of course ... FP45, which has no rifling, is only worth 2. 1 USD, but it's best not to treat it as a serious pistol.
