Holosun's warranty process is painless and smooth. I had a coworker leave his new 19 MOS and new 507C V2 (fortunately unloaded) on the roof of his car and drive off, causing is to fall onto concrete at residential street speed. Same result: delamination in the corner, held zero, still worked. Holosun sent him a replacement and he returned his. This was July-ish.
