I bought this tool at Gander Mountian for $10.00. It is indespencable and I feel should have came with the rifle to start with.
I tried to get one from the Remington store and was told they don't have them any longer.
I then had my favorite gun shop try to get me one thru their suppliers and they came up empty too.
I was shocked when I saw them at Gander mountian, but really happy too.
If you go to the 209 kit use the Canadain one sold at Cabelas.
I think I saw a test done with BH 209 in a remington and the results were not good due to the blow back if I remember.
