Its not even close to semantics. Its a specific design with specific features.
Its like someone taking a 12.5 AR upper, and dropping a non DD rail on it and calling it a MK18. No sorry bud, its a 10.3" with RIS II rail.
Its ignorance pure and simple. You can't just call anything anything you want because it has a part or two in commonality. Otherwise we would all be shooting "glocks" "AK47's" and "assualt rifles".
Like the Patch btw. 29th is one of my SSI's.
I agree with you. I know the Marines used 20" barrels on the SAM-R's. But you make a good argument....
