No more wasting time picking up brass! - Caldwell AR-15 Picatinny Rail Brass Catcher

Works great on my SBR with red dot. Does not affect weapon cycling or bolt lockback. Perfect for shooting expensive brass like 300 BLK. Holds its rigid shape thanks to the wire frame, even while holding dozens of rounds. And fitment is secure and flexible thanks to its Pic rail design. Very convenient at outdoor ranges. But it's a godsend at indoor ranges. Yea it's more than twice as much as the cheaper flacid velcro models... but it's also more than twice as good!
