You mean the sexy Honey Badger, right?
The Colt Commando is a Vietnam/Cold War era weapon, and has since been overshadowed by the M4. But the Colt Commando is basically and M4, and guess what? So is the AAC Honey Badger.
Actually the AAC is an M4. Just a silenced PDW version of it. Take a look at this COD: Ghost Trailer and go to 0:55 and look at the left screen. Remind you of the first-person view of a certain rifle?
Love the Honey Badger. For he already loves you.
3:03 is actually using the M4A1 model from MW2. The HK416 also doesnt have a barrel-mounted flip-up front sight, so if you don't believe it's the old M4, that should tell you it's not a 416.
3:46 is the APS (which happens to use part of the Ak model from MW3).
The acc honey badger is not the typical ar15. It does not shoot 556 ammo like the standard ar15. It shoots 300 blackout ammo. This ammo at supersonic loads out perform the ak 47 with knock down power. Therefore it's damage should be high like the ak 47. If it is shooting subsonic ammo the it performs like any other sub gun. It all depends on which ammo will be used.
