The Spikes Tactical ST Dynacomp Extreme Suppressor is 2.25" long. So it could be pinned and welded to a 13.9" barrel.

CAN it be? Yes. But it will not get you to 16”. 13.9+2.25 is 16.15. MINUS the 0.5” of threads that overlap is 15.65”. That missing 0.35” will be important. Your best bet is to go with a 14.5” barrel or a muzzle device at least 2.6” long.
