Prevent flying shells from distracting you or others. The all steel Save-It Shell Catcher captures the empty hull when ejected through the receiver and holds the empty for easy removal. For use with all 12-gauge semi-auto shotguns. Soft, padded tape acts like a barrier; keeping the metal plate away from the gun. Wire catcher locks in up position for singles, turns down for doubles or pulls out for hunting. Easy to use and works great! *Designed for right-handed shotguns only. Not intended for left-handed models. Wire can be bent closed while wire is not in locked position to fit 20-gauge semi-auto shotguns.
