The Usa aftermath does have a 12" barrel with a slight endload, not much. I personally think the 2015 usa aftermath is better than the 2016. But the '17 Asa lineup is out of control fire. There are a few exclusive models out there that are something special. Look for the Future, Insane, or Omega's, all have crazy pop right out of the wrapper. Good luck! Let us know what you decide.
