In fact, during World War I, there were several semi-automatic rifles on the battlefield, but the number of equipment was very small compared with five bolt-on rifles, which was completely negligible. For example, there are Mao Se M-/KOOC-0/9/KOOC-0/6, RSCM-/KOOC-0/9/KOOC-0/7 and Winchester/KOOC-0/907.

During World War II, American M- 1 Garland, German G-4 1/43, Soviet SVT-38/40 and other semi-automatic rifles were all famous semi-automatic rifles at that time, and their performances were greatly improved compared with those of Mao Se M- 19 16 during World War I.

Enlarging a revolver into a rifle really has the principle of this revolver rifle. In fact, it is almost the same as a revolver, that is, the barrel of the revolver is lengthened, and the handle of the revolver is changed into a wooden stock, so that it can be shot side by side and become a real rifle.

However, due to the inherent shortcomings of revolver rifles, such as poor sealing, the gap between the nest and barrel of 5 or 6 rounds of ammunition is large, which will lead to air leakage and smoke when shooting, which will really smoke the shooter's eyes. As long as we continue to use honeycomb as ammunition, we can't really solve this problem.

Because of the natural defects in the structure of revolvers, revolvers used in melee or self-defense are the most suitable ones, but they are not suitable for rifles. Therefore, after being used by military police, revolvers are not easy to use. Revolvers such as Colt M- 1855, which appeared in history, are as fleeting as meteors on the gun altar.

Colt M- 1855 revolver is actually an enlarged version of revolver, with a capacity of 5 rounds. The barrel of the revolver is lengthened, and the size of the bullet nest is also increased, so that a larger warhead can be inserted.

This gun was purchased by the U.S. federal government with 4,700 guns and used in the Civil War. But in fact, Colt M- 1855 revolver rifle is not reliable, there is a big gap between the bomb nest and the barrel, and there are a lot of flames and gas leakage when launching, which seriously affects the shooting accuracy, including the effective range.

The appearance of five-bolt rifles actually blocked the survival and development space of 5-6 unreliable revolver rifles. The five-bolt rifle immediately became the standard rifle of various countries' armies, while the revolver rifle was completely eliminated, and it was always difficult for the revolver rifle to become the mainstream infantry gun in the army.

Whether it is a lever rifle, a latch rifle, a semi-automatic rifle or an automatic rifle, it is better than a revolver rifle, and its range, including shooting accuracy, is above that of a revolver rifle.
