I had to buy one this summer for the first time. I shoot a scott rhino and after about 4-5 years with it shooting more days than not, the pin that holds the head in came out early this summer. I put it back in adn it seemed solid but with a Sept elk hunt coming up I was nervous. Happened again about 4 weeks later and this time I lost the pin. Bought another from Scott, if I was smart i would have bought two since they don't make that release anymore and I got lucky with one found in the back room.
