Hi Cory, thank you for your feedback. We're sorry to hear about the issue with the nylon cap nut. Our installation videos caution against torquing it down because it's nylon. We don't use a metal nut because of that exact reason. People often over-torque it and crack the riser. If you'd like a replacement nylon nut, we're happy to send you one free of charge; you'll just need to pay shipping. Email me at karenellis@jaktgear.com, and I'll be happy to help.
