Am listing for one of my good friends who is not a "computer person" as he tells everyone. He used this set a half dozen times and finally had me send his 28 ga Browning barrels to Briley for a set of full length 410 tubes. They are back from Briley and he no longer needs these. Am posting some pics except for the O-rings which he forgot to give me but will be included. He is asking $210 shipped which I recommended as the asking price. The 28 to 410 is definitely the most effective Chambermate set up for the shooting of 410s in Sporting Clays. I shot a US Open at Hopkins with 28-410 Chambermates with a loaner set from Seminole.
