Picking up your empty cases at the range is not only time consuming but a real hassle - until now! With the AR-15 Pic Rail Brass Catcher mounted on your rifle's Picatinny rail, cases are ejected straight into a collection bag for disposal - or reloading - later. Unlike traditional catchers, the AR-15 Pic Rail Brass Catcher has an aluminum clamp and steel wire frame that are fully adjustable to work with almost any rail and optic configuration. The bag will not interfere with bolt function or cycling. Ideal for reloaders - no more scrounging around the range to get your brass back!
