Is the service life of firearms made in China far worse than that in the West? How long is the service life of modern firearms?

Rifles can be used for many years in peacetime. For example, the Indian army in the picture below even equipped its second-line troops with Mk.4 bolt-on rifles in the Li En field in World War I. Some netizens joked? Can the rifle be oiled again 100 years? ,? The plump patina on this gun can destroy the whole Panjiayuan. ?

To know the answer to this question, we must first know that the service life of firearms can be divided into design service life and actual service life. The first is the design service life of firearms. Due to the influence of technology, materials and design performance requirements, the design service life requirements of different firearms in different countries are different. Taking domestic firearms as an example, the design service life of ordinary pistols such as Type 92 pistol is generally 3000 rounds, and that of automatic rifles such as Type 95 rifle is generally 10000 ~ 15000 rounds.

In foreign countries, the design and service life requirements of firearms are often higher. For example, the design service life index of American M9 pistol is not less than 5,000 rounds, and there will be a set of strict testing procedures. Generally, three M9 pistols are selected, and each M9 pistol needs to shoot 5000 bullets. During the period, barrel cooling and maintenance can be carried out according to regulations. Finally, it is required that the total number of gun failures of three M9 pistols after firing 5000 rounds is less than 12.

The design life of foreign assault rifles is longer. For example, the minimum design service life of the L85A2 rifle is 10000 rounds, and the maximum design service life is 25000 rounds. The design service life of SCAR assault rifle is 15000~35000 rounds. Another example is the well-known HK4 16 assault rifle, which has a designed service life of more than 20,000 rounds. However, in the actual test, the HK4 16 assault rifle is still very intact after firing 26,000 rounds, and the quality is really amazing. Some time ago, the Germans set the design service life index of their new rifles at more than 30 thousand rounds. Obviously, there will be assault rifles with longer design life in the future.

Having finished the design service life of firearms, let's talk about the actual service life of firearms. The designed service life of the above firearms is actually only a theoretical value and a performance index requirement. Just because the designed service life of a gun expires does not mean that it can no longer be used. On the contrary, most firearms can still be used for a long time after the design service life expires. However, after the design service life expires, the shooting accuracy may become lower, the initial velocity may become smaller, and the failure rate index will gradually increase.

Generally speaking, the actual service life of firearms is not only affected by the designed service life, but also related to its use environment and maintenance level. If it is used normally in the general training ground environment and carefully maintained. Then the actual service life of this gun will be very high, at least 2 ~ 3 times of the designed service life. The maximum number of bullets that a rifle can shoot mainly refers to the actual service life of the rifle, and there is no very specific value.
