Yup, I had that disappointment when mine started leaking. Yes, I had that apprehension of opening up a brand new rifle, but I do enjoy finding out what makes them tick. If you do decide to fix it yourself, you can order complete o-ring kits from "across the pond". It is an added expense for a brand new gun but it worth it to me. Gamo / Pyramyd Air / BSA should get a few of these kits shipped over here and make them available for a discounted price - just a good customer service thing to do. If you live near MD, send me a pm, bring your R10, an o-ring set, and a beer. We can spend a little time to fix your leak, take it out back to try it out, talk about AG's over that beer and I've made a new friend.
