Title: Armalite AR 15 flat top 20" barrel, QUESTION?
Post by: TeacherMan on December 21, 2012, 04:46:16 PM: I know someone that was fortunate enough to pick one of these up this week and we are trying to figure out the barrel twist on it? We don't see it on the side of the barrel. All it really says in .223/5.56.

Does anyone know what the barrel twist is on them? Could a gun smith tell them?

thanks

I was looking on midway today, they still had some in stock. I think they had some 50 packs of 52g hpbt by hornady. Pretty decent price as well.
