That's correct. A chamber that is cut for a specific round dimension is ALWAYS going to be more accurate than any type of combination chamber.
The thing is though, with a 16" barreled AR-15; you aren't going to be shooting sub moa groups and you aren't going to be hitting soda cans at 500 yards. That is not what you are building.
My next question is about barrels. Theres stainless, chrome lined, non-chrome lined....what does everyone here recommend? I'm assuming the stainless is the easiest to maintain, but I'm up for suggestions and experienced insight.
A chrome lined barrel isn't as accurate, as has been discussed on numerous occassions, it was designed to handle heavy, full auto, constant rounds down range. The nice thing is, again, you aren't building a benchrest rifle here, so in a "field quality" AR, that you can shoot Minute of Bad Guy all day long, there is nothing wrong with a chrome lined barrel.
Now, if you are building Varminter, with a 20" barrel, sure go with a S/S Douglas or Shilen, or a precision cut rifled barrel from one of the great makers up in the Wisconsin/Minnesota area ( Mike Rock / Krieger ).
But, for a Standard build, 16", home defense, paper punching rifle - there is nothing wrong with having a chrome lined barrel. It won't be AS accurate, but for Minute of Bad Guy accuracy rifle, there won't be anything to worry about and you will get good, long term use from it.
