The T&S Shell Catchers, by Birchwood Casey, catches single shotgun empties and allows you to save them for reloading. T&S Shell Catchers prevents empty shell from being thrown towards the next shooter and stops empty hulls in the ejection port at an angle that allows for easy removal. This part snaps easily to the side of the receiver, just below the ejection port, and snaps off when you need to cycle more than one round.
