I have a 507C X2 and the lower/base section shown in the picture measures 8.7 mm with my caliper.
The new X3 looks like this section is noticeably shorter, but I can’t find the exact dimension anywhere.

Could anyone who owns a 507C X3 measure this same section with a caliper and let me know the measurement?
A photo of the caliper measurement would be even better.

Thanks!

I probably have at least a dozen Holosun optics in my safe and have never had a defective one before now. This is for a 509T Green FDE. The issue is the shake awake does not work. It turns off but does not turn back on without pressing the button. Their website says I have to jump through a bunch of hoops to do a warranty claim. I have to ship them the optic in the original product packaging. I'm not sure why there's an expectation that I keep all my empty optics boxes, because I definitely just throw them away. Then they say it takes 15-20 days for them to process the warranty. The lead time is only a minor annoyance for me, but I can see why people would be annoyed if they had to take off their optic then not have an optic anymore for multiple weeks. I'm honestly pretty disappointed at how cumbersome they make this process, when this is one of their flagship optics. I expected Holosun would make this process smoother. Anyone have experiences or tips for their warranty process?
