User blog comment:Argorrath/Treyarch confirms that there will be no more gun DLC/@comment-50.128.196.58-20130410122659/@comment-5607850-20130410135923

The HAMR, QBB (or whatever that chinese lmg is called), and the Scar-H actually fill the roll of an AR/ LMG Hybrid.

I agree though, we should have some Weapon DLC.
