I have an AAC EVOLUTION (left hand thread) which is currently in use with my usp tactical however I would love to get it up and running with my 45C. For I think it would be a sweet combo as the 45C is an amazing shooter and I can just imagine it suppressed -- probably just amazing! Could anyone suggest any sources where I could acquire a threaded barrel for the 45C? I've conducted a few generic google searches however have not had any luck locating a barrel -- especially any in stock. Thanks in advance!
