Okay, and after market has one advantage over factory ported since you get to choose your suppressor—but price is about the sames unless I get a pre-threaded barrel like the AAC (which I haven't found yet locally).

One last question: barrel length. Here is what I know (and don't know):
1,000 yard terminal velocity is at the limits of 308 to stay super-sonic and we've got nutation and precession (from wind, drag, etc.) taking it's toll and probably key-holing no matter the barrel length. Thicker barrels cut down on the barrel wag but of course are heavier but longer barrels give better initial velocity. Ballistics tables are theory though accurate. What is better a 20" SPS TAC bull barrel or a 26" SPS Varmint barrel or the 22" VTR Varmint? I want the best I can get with reasonable weight for 1,000 shooting.
