I have a suppressor on order and now want to look at going to a 14.5" M4 length barrel and pinning the Phantom QD flash hider. Anyone have a recommended armor in the Denver or Colo Springs area they could recommend to do this? Basically want to compare the cost of having my existing 16" DPMS barrel down or buy a Daniels Defense 14.5 barrel. Either way, it would still have the carbine length gas port so I dont see any issues with that. Any of you actually get a 16" cut down that can speak to any accuracy changes? THx!
