sgtar15,
That is a very good question, me myself I've always had the longer barrels and when I pull them out in front of others I hear them remark and comment, sometimes negatively. They would say "That's too long" and I would reply "Well, do you like my bulbus muzzle brake?" And they would always tell me that they prefer "postban". Gee, what's a guy to do? So I created my own support group, www.largebarrelsupportgroup.com. It's really helped out a lot.
