I too just bought the bracket and merc insert today. I looked at that hose and figured out, according to the user manual, that you need to shave off a section of that tube. I got it installed and am going hunting next weekend, wheather permitting. I have had my Nova for 2 years and its the best firing gun I have ever had. Well worth the 3 hondo I paid for it. I now see that Gander mountain and Cabelas have jacked up the price 75 buck this year. Has anyone used the recoil reducer yet? Any noticable difference?
