Personly, keep all mw2 weapons but replace The mp5k with the mp5 take out rangers and 1887's. Give the ak-47 its cod 4 skin. same with the M4A1. All so, give the AA-12 a twenty round c-mag magazine and change its rate of fire to 350 rounds per minute and take out the TMP, its a copy of the Mini-uzi! plus i want the M240 replaced by the M249 SAW, just for the realism.
