The AK-47... the longest serving assault rifle, with a high-powered 7.62x39mm cartridge, low production cost, simple mechanism and ungodly reliability, the number of units manufactured is into eight figures now, and with all the (albeit very diminished in recent years) clamour among the NATO nations to come up with something to replace the M4/SA80, many designs have come and gone from use (e.g. G3, FN FAL & SG-540) or are used by very few organisations/in low numbers (e.g. Galil, FAMAS & F2000), it leads me to...
Question: When (if ever) will the AK-47 go out of use?
It hasn't been in very widespread use, actually. The AK-47 went into service with the Soviet military in 1949. In the '50's, it had already been replaced by the AKM, which was almost identical, but still not just an AK-47. It still used the same decent firepower 7.62x39mm round, but had some upgrades that pushed it beyond a variant of the AK-47. In the 1970's, the AK-74 was introduced, which was chambered for the 5.45x39mm round. This is still the standard service firearm of the Russian military (AK-74M), with the AKM being used as a heavy rifle by some troops in urban combat because of its ability to penetrate thicker cover than the -74.
However, it is not one gun that has outlasted the others. Yes, the AKM is the most widespread and most manufactured weapon in the world, however its service life was no longer in reality than any other weapon. There are rebels today using older rifles than the Kalashnikov to be sure.
In fact, what will live on is the Kalashnikov family of rifles. This is simply because of the design of its mechanism, and reliability. To say a Kalashnikov is outdated is to say rotating bolt is outdated. The mechanism type is what lives on, but the guns themselves are going through changes all the time, as with any other weapon. Take the AN-94, for instance. It is a development of Kalashnikov's design, but it is not an AK-47. This is in a similar manner to which the FN SCAR-L Mk-16 is to replace the M-16A4 as the service firearm with the US Army Rangers within the next decade, though, of course, the SCAR is not an AR-15 family rifle. It is, however, about as similar to the M-16A4 as the AN-94 is to the venerable AKM or AK-74M.
