In game, the AK-74M is by all standards an average assault rifle with fairly manageable recoil but slow fire rate. Unlike other assault rifles, the AK-74M features a hefty 40-round magazine, making it a flexible weapon choice for critical situations. Nomad's Airjab Launcher prevents the rifle from equipping any foregrips.
Despite the fact that it is refered to as the AK-74M, and the text blurb about it mentions that the gun uses a lighter caliber, the model for the gun is actually a Century Arms WASR-10, which is an American-made clone of the AKM chambered in 7.62×39mm.
The weapon model has the words "WASR-10 Cal. 5.45×39mm" written on the side of the receiver. In reality, only the WASR-2 variant is chambered in 5.45.
Additionally, as they were intended for the civillian market, WASR rifles are semi-automatic only.
As stated above, the magazine also used to be a more curved 7.62×39mm, and eventually swapped to a straighter 5.45×39mm magazine. This change was appropriate for an "AK-74M", but does not remedy the fact that the WASR-10 itself does not chamber 5.45mm, nor the fact that only certain WASR-10 rifles can actually accept conventional double-stack AK magazines.
