Help with modern warfare 2 ault cl?(read description)?

Just help me with telling me what to put, since im in the 2nd prestige i have all the pro's unlocked and almost all gun since im lvl 62. Any help with a cl, include perks and guns, no ACOG scope dont like those. Im a run-in-gun player, that rushes often but also stays back, if this would help in your answer. Mainly i need an ault rifle cl, since i use intervention with fmj. Thanks to all that help.
