How's about buffing the M1 Carbine? Perhaps the melee range could be increased a good bit, that'd be an interesting way to balance out the painfully long reload and small clip. And maybe buff the damage on shooting but somehow keep the melee the same, and possibly nerf the firerate/freeze so it goes through the whole bolt pulling animation. It could be like a mini DSR with a bayonet. Any buff would be justified by the fact that it's more expensive than AK47 but is substantially worse now that AK got buffed.
