I have a few questions here regarding this topic. First off if I were to purchase the ops-4 side charging upper (which is build for a 5.56x45) could I just swap the bolt and firing pin out and build the rest of the rifle around 5.45?

Also has anyone else heard about this company and if it reliable or not? They showed off a side charging ar15 carrier which was according to them available in 5.45x39. But when I went to the website I can't even find it.
