Tired of picking up .223 brass from your AR? The AR-15 Brass Catcher from Caldwell 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. Also works great in preventing hot brass from landing on shooter or other people next to the shooter. The catcher's wire frame holds the fabric in the correct shape and allows brass to enter the bag without disruption to bolt function or interrupt cycling. Convenient zipper at bottom of mesh bag makes emptying simple. Captures and holds approximately 30 rounds.
