Tired of picking up brass from your AR? The AR-15 Brass Catcher attaches to the forearm of any AR with hook and loop webbing and captures the ejected brass. It prevents brass from being scattered around your shooting area, and works great in preventing hot brass from landing on shooter or other people next to the shooter. A wire frame holds fabric in correct shape and allows brass to enter bag without disruption to bolt function or interrupting cycling. The Caldwell AR-15 Brass Catcher captures and holds approximately 30 rounds, and has a convenient zipper at bottom of mesh bag that makes emptying quick and easy.Notice for California consumers: Warning:Cancer and Reproductive Harm -www.P65Warnings.ca.gov
