The Universal Brass Catcher is designed to save you time and money at the shooting range. Simply place the Brass Catcher next to your firearm and begin shooting. The brass will be ejected into the high quality Monorail net system. Because the Universal Brass Catcher does not attach to your firearm, it will not interfere with proper firearm function. The Universal Brass Catcher can be used from a shooting bench, prone, or offhand.
