Spent primer catcher for the LEE Breech lock challenger (old style) Now your spent primers can go down a tube instead of the hard to clean out catch tray area. Just clip on this catcher and attach a 1/2" ID hose! Spent primers go into the catcher then down the tube spout. NOTE: 1/2" id Hose NOT included (hose can be purchased at any hardware store) NOTE: Press not included in this listing. This catcher is for the old style lee breech lock press, see pictures. (Item is 3d printed and may show small layer print lines) View my store for more lee and other press items. thanks for looking
