Has anyone else had trouble using the Barnett crank? I put one on my Ghost 400 and the press fit pin that controls the cranking fell out. It is also suppose to prevent the crank from unwinding. First time I tried cocking my Ghost, the crank got stuck on the pin and then it released unexpectedly nearly breaking my thumb. Is this just a defect or or all the cranking devices like this? I just dropped it off at a pro shop to make sure that the crank is installed correctly. The pin is bent and probably toast.
