The PKM's only redeeming feature is its relatively high damage, but due to the awful accuracy mentioned earlier it's only good up to around 10metres. If an AR is only useful for room clearing clearly something has gone wrong.
Most of the PKM's problems stem from two things, firstly that it is a stock bf2 weapon (one of the few remaining in PR) and secondly that it is a general-purpose machinegun, not the LMGs of most other factions. If you tried to put the M240 in game as an infantry weapon I imagine you would have similar issues. The russian forces already have an LMG in real life, it is called the RPK-74m:

Anyway, short of replacing the PKM, what can be done about its failings? Well for starters it needs lower recoil, the MG3 for instance fires 7.62x51 NATO rounds, which are nearly as big as the 7.62x54mmR bullets of the PKM. The MG3 has very little recoil and a massive rate of fire, the PKM is worse on both fronts, why is this?
Secondly, the main benefit of having a GPMG in the first place is reliable long range fire support. Without an accuracy buff the PKM cannot provide this, since its (presumably realistic) low rate of fire precludes it from truly effective suppression, at least let the damn thing kill once in a while.
If the Russian military advisers believe that the RPK would be a more valid AR then the conversion from the current Al-quds model would probably not be too taxing. However, if the PKM stays it needs to be improved significantly.
