At a recent range day I noticed one of my top caps to my 1 piece talley rings was cracked. These rings are at least 10 years old, sit on a Kimber Montana 325 WSM, and generally get the snot beat out of them every year on the quad and hiking around rockslides etc. So I reached out to them more to just see if I could buy just the cap and they had one in my mailbox two days later free of charge. Nice to see a company go above and beyond for customers. Have at least three sets of these and never had an issue till now.
