No, it has nothing to do with you ordering a barrel.
I don't even know you, how could it have anything to do with it ?
If you would have asked me however, I could have easily told you why I have two uppers that I am going to switch barrels on.
The two uppers in question are post ban uppers. The flash suppressor is permenently attached.
I own an AAC M4-2000 suppressor which uses a proprietary flash suppressor which allows you to quickly attach/detach the suppressor. I can't put these flash suppressors on those two uppers since the ones on there are "permenently attached". Thus, I can't use my suppressor on them. So, I am changing out my post ban barrels. While I am at it, I would also like to go to 1:7 barrels, but if I can get another barrel that I want in trade for one I already have, then I can overlook that aspect of it.
Simple answer to a question never asked.
