SME Brass Catcher with Heat Resistant Mesh | Durable Versatile Picatinny Mounting Shooting Gun Accessory for Re-Loaders

Mounted On a AR 15 platform w/a 3x9 Leopold scope. Had to do a little fileing to make it fit but it beats picking up brass.

I can't attach it to the rail. The screw has a nipple in the center that won't allow any tool to fit inside.The basket looks good and should work well.
