For accuracy, power, and recoil the M240B with a foregrip is the best LMG. The M60 and PKP are 7.62 as well but they just don't compare. The PKP has so much recoil it's literally useless. I just started using the M36 so we'll see how it handles.
As for the Assault kit the AEK-971 is the best gun by far. You have to have the AMMO specialty though because it rips through rounds incredibly fast. I run mine with a Kobra RDS, underslung rail / M320, and a long barrel. Got a 23 kill streak with it lastnight
