I know aimsurplus does that with their new products that no one has had time to review yet. never hurts to ask.
Every upper on that web site that I've looked at says the specs. 5.56, 1 in 9 twist ect. Also, 5.56 is not going to cause less accuracy. A barrel chambered in 5.56 will allow you to shoot a wider variety of ammo without worrying about over pressure. With a 223 chamber you should never fire 5.56 ammo. All that being said, I don't have any experience with AR15depot.com.
