300 Whisper Build Question?
Hello this is my first post here. I know this has been covered before and I have looked at the previos posts but here is the question. I about to build a 300 Whisper upper for my AR-15 and I am looking for a 16 inch barrel. I will be using the upper to shoot subsonics along with a suppressor. I want a barrel that will be capable of at least 1 moa with subsonics. I have looked at the fatory offerings as well as AR15barrels.com, Noveske, and Mike Rock. I would like to know if anyone has any experience with these barrels in 300 Whisper using heavy 200gr to 250gr bullets. If so please let me know what twist and what type of gas port you are using for the barrel. Any information would be greatly appreciated.
