I was under impression that as long as a flash hider is made out of a same barrel and no separation between two. it is consider as a part of the barrel. I am asking about this because I want to keep it as a Minimum length ( 18. 5 inches ) as possible with a g36 k type flash hider. However, I have been told that an actual barrel length is based on a rifling and it can not be disturb. Could anyone help me with this?
