Must have brass catcher - Caldwell AR-15 Picatinny Rail Brass Catcher

This is my second purchase of this brass catcher. I use them on my AR rifles. .22, .223/5.56, 9mm, etc. They are small, easy to install, easy to nap on and off, easy to empty, and work flawlessly. They do not get in the way of you rifles action and are essential if you want to save your brass. I have a range in our backyard, and shooting stations on our back deck. Now, when our children and grand kids practice we don't have to police our brass when we are finished shooting. The brass catchers help contain the brass. Now we need to research Caldwell's brass catchers for pistols.
