I'm confused as to why anyone would buy an AR with a barrel longer than 10.5".

I see a lot of comments in this sub saying 16 inch barrels are superior, but I've found the exact opposite to be true. <br>I have a 10.5 with an SBA3 brace and I can shoot it faster and more accurate than my 16 inch AR with a stock. <br>I would go even shorter but I don't want to deal with the stamp and wait time.
