My wife and I have decided to take up firing at the local range on the weekends. I have been talking about owning firearms for some time and are ready to take the plunge. We are considering his and hers hand guns and one fun to shoot rifle. I'm active duty military and personally love the colt M4, however most of the ones that I have seen all have a 16" barrel. How do I go about owning one that is 14.5" we live in the state of Georgia. Any help will be most welcome. Thanks.
