"The whole of the Bill (of Rights) is a declaration of the right of the people at large or considered as individuals.... It establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of." (Albert Gallatin of the New York Historical Society, October 7, 1789)
"A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington
The old boys at the range I go to just put a towel over the ejection port area/upper receiver and it catches the brass. I know you said you didn't want to do this, and I'm sure it's a PIA out in the field, though.
Tango,I have a couple of these. They aren't the best things in the world,but atleast you can keep all your brass in the field or at the range.What brass that doesn't go into the bag just falls straight down.
