This article is the Kalashnikov Group Kalashnikov Group, or rather, Kalashnikov's U.S. privatized subsidiary released a video on October 1, which talked about the difference between ak103 and ak47, and the dog also used this video to talk to everyone about it.
As of AK103, Kalashnikov's AK has gone through four generations. They were the Ak47, which was mass-produced in 1949; the Akm, which was produced from 1959 to 1970 after the simplification; the small-caliber Ak74 after 1974; and the Ak100 series in the 1990s.
(The one on the right in the picture is akm)
The first note here is that the ak103 belongs to the ak100 series, which is only a standard rifle of 7.62x39mm. The AK100 also includes the AK101 and 102 that emit 5.56mm; the AK-105 that launches 5.45, and even the AK74M also belongs to the Ak100 series family.
The muzzle of the ak100 series has a muzzle brake similar to the ak74, and the utility is divided into two stages, the first is that gunpowder gas is sprayed out from the three holes of the arrow, especially the upper hole is used to suppress the muzzle jumping up; and the large opening hole in the front is to let the gunpowder gas hit the front wall, slowing down the recoil. This brake greatly increases the stability of continuous firing, and the effect is more than akm's miter anti-jump device, and the ak47 does not even have a muzzle device.

There is also a difference between the ak47 and the ak103 in the barrel, at least before the ak100 series, the barrel rifling of the ak family was made by die extrusion, but the die will stress the barrel when pressed into the barrel, so the accuracy is not good. The ak103 uses cold forging, in addition to making the metal crystal particles tighter and stronger, the accuracy performance is also better (specific rifling process to find opportunities to say separately)
Of course, the biggest difference between the two guns is the material of the butt of the handguard, there are many wood resources on the maozi side, and the high-quality beech oak is a good material for guns. But it is a piece of wood after all, heavy, wet and dry will shrink, dry and crack, but also easy to catch fire. But ak103 is a polymer with glass fiber, light, tough, resistant to high and low temperatures, and not easy to burn. Even the magazine material of the ak103 is this, but the two magazines can be used universally. In addition the ak gun body is roasted blue, while the 103 is more durable with modern phosphating treatment
The original ak47 did not have a mount to mount the sights, but each of the ak100 series had side brackets
There is also ak itself a complete set of rifles including the re-entry spring that is mounted in the receiver, unlike the ar, the stock also has a re-entry spring, so there is no reason not to use a folding stock. Therefore, since the AK100 series, including the later Ak200 to the current AK12/15, it is all folding brackets.
If akm itself means modernization модернизи́рованый), then ak103 is an improvement on the basis of akm some of the concepts of ak74 (such as flame suppressors) and modern processes and materials. But in essence, the interior is still a 7.62x39 ak, it is true that the recoil is added to make his recoil small, and the cold-forged barrel makes it continue to fire and accuracy, but the ballistic trajectory of this intermediate power bullet is too poor, and it is funny compared with modern small calibers.
Therefore, the Russians themselves only procured a small batch in the field of special operations (with silencers + subsonic bombs or large calibers), and the main force still used 5.45mm ak74mn. Up to now, the Russian army began to replace the small-caliber ak12 in batches, and the Ak15, which was also 7.62x39, was only a cold bench + foreign trade goods.
