Caldwell Universal Brass Catcher SA. Once the brass falls into the bag you can easily use the zippered bottom of the brass catcher to easily remove the casings and recycle them. The double hook and loop attachment system is compatible with both bolt-action and semi-automatic weapons and the bag is heat-resistant so it can hold up even when it's loaded with hot brass. Its swing-open design allows you to easily open and close the bag without disrupting the bolt-action or blocking the gas port and the internal cage design maintains the bag's shape. The brass catcher utilizes a Swing-Open hook & loop attachment system allowing you to remove the brass from the bag with just one hand. The result is zero brass spouting which is great for storing for reloading later. The Caldwell AR15 Universal Brass Catcher SA is a highly effective means for capturing your brass without having to constantly bend over or bend over yourself.
