In game, the AK-74M is by all standards an average assault rifle with fairly manageable recoil but somewhat of a 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 unable from equipping any foregrips, making recoil slightly harder to control than other assault rifles.
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.
