Use something faced paced for weapons. Id recomend TS (NEKram's weapon pack) or Warfare. HK is eh to me. Defiantly not Walters BF3 pack. Blockombat is pretty good except for slow fire rates and ridiculous recoil. Dont use that modern firearms pack that came out recently, its just a reskin of the BF3 pack. Tier Tactical would be okay, its just that its over used and over rated IMO.
