SBR AR15 barrel length?
Did not find a specific post on this so figured I would ask with a poll.
What Length are you running for .300 blk in AR15?
What position is Gas port, pistol position or shorter?
Does it cycle without can for subsonic?
I have 16" barrel with carbine gas port and like it a lot, but I have an SBR and want to get one hopefully before next year hunting season, and trying to figure the most used lenght.
