What's the difference between AK47 and AKM? I looked at the picture for a long time and didn't see any difference. Please ask the master for advice.

There are four differences between AK47 and AKM:

1, look at the muzzle, AKM is oblique.

2. According to the shape of cartridge case, AKM adopts punching and riveting cartridge case and AK-47 adopts milling cartridge case.

3. Check whether there are exhaust holes on both sides of the piston barrel.

4. Look at the constellation shape. The hole of AK-47 piston cylinder is rectangular, while the hole of AKM is square.

Extended data

AKM is actually an improved AK-47 with better performance. Its official Soviet name is only AKM(AK47 is called AK47 because it is fixed at 1947, where A stands for the initials of Russian automatic rifle and K stands for Kalashnikov).

Although many people simply call it AK47 because of its similar appearance (in fact, it has become a conventional name), it needs to be clear that the AK with the largest output in the world we introduced is actually AKM.

After successful development, the AK47 quickly became the standard weapon of the Soviet Union. However, there are some problems in the use process, such as large recoil and poor ejaculation. AK's father Kalashnikov immediately led his research team to transform it. 1954, the third improved version of AK47 was successfully finalized and named AKM. Until 1959 began to equip the troops.

The overall structure of AKM follows the design of AK47, but some key points are optimized. Firstly, AKM adopts forging machine and casing, thus reducing the weight of the gun from 4.3 kg to 3. 15 kg. Moreover, on the shell, AKM also welded the barrel socket and the tailstock tip.

Unlike the AK47 bolt locked in the case, AKM's shooting is locked in the socket of the barrel. As for the machine gun guide rail, AKM uses stamping parts, which greatly reduces the manufacturing cost. In addition, it is worth mentioning that AKM is equipped with a reducer to replace one of the two hook stoppers of AK-47. Once the safety stopper can't be pressed under the shooting frame, the reducer will buckle the hammer backwards and realize the deceleration effect through its inertia.

Americans have studied the difference between AK47 and AKM, and conducted shooting experiments respectively. By comparison, it is found that AK-47 will rebound slightly when it is in place near the lock. As a result, AK47 occasionally appears blind fire in continuous shooting, and the test of AKM proves that the above problems have been completely solved.

Through this improvement, AKM is more portable, with fewer faults and higher accuracy, and can better adapt to the battlefield. AKM can be roughly divided into two models, the first is the model of AKM fixed wooden frame, and the other is the AKMC metal folding frame. On this basis, there are also refinement types that adapt to different combat tasks.
