I too ordered a WOA barrel the other day, though I am headed in a different direction. I will be building a dedicated predator (coyote)hunting upper. I ordered a 16" lightweight barrel with a mid length gas system. I have humped enough miles with heavy rifles that I can really appreciate a light one.
WOA uses Wilson blanks. I have heard very good reports about WOAs quality so I decided to give them a try.
