Please advise me on this ACR setup i use mostly in FFA Modern Warfare 2.?

I use an ACR with a silencer , scavenger pro, cold blooded pro and ninja pro with akimbo model 1887 shotguns as secondary, claymores and flash grenades. My game play revolves mostly around controlling small areas , closing off entrances with claymores and camping. Please advise for or against this setup.
