Long time shooter, first time builder. I am building a 300 Blackout. Trying to decide on a barrel. It seems like every time I decide on something I read a post that someone else contradicts it. The two items I cannot decide on are gas block length and twist. Originally I was going to buy a 16" 1x8.5 twist with a adjustable pistol length gas block, however many forums say carbon length will work just fine and buy a 1x11. So, if anyone has hands on experience with a suppressed 300 blackout I'm all ears. Thank you.
