The AK-74 is a modernized AKM.
The AK-74 should actually be just as durable if not more durable than the AKM as it is a smaller caliber as well as an improvement over the AKM.
The built in muzzle brake, and low recoil of the 5.45x39 means this weapon should be very controllable in recoil and sway.
Since it’s firing a smaller round.. and the suppressor in game was actually made for it, it should be more durable. Instead of being a meager 166 rounds from Pristine to ruined, it should be closer to 200 (especially since real life suppressors last a few thousand rounds at least).
Lastly it’s damage is reasonable in game.
