The M1 Does My Talking
FFL's have different opinions on what an H-Bar is and may want to sell what you think is unregulated as regulated. If you disagree with their opinion, either accept it or look elsewhere . Their shop-Their rule. Arguing your opinion is a waste of time.
Why pray tell are you quoting me?
You didn't think I was saying anything at all about anything remotely related to your comment, did you?
I was merely clarifying the origin of the "HBAR exception". It's a relic from a long ago time when only four ARs models existed, and all four were made by Colt.
