This is rated up to (and including) .308. Anything over that is not guaranteed by FLIR.

I contacted FLIR regrading this scope and asked them if would handle a .308 caliber and they assured me it would. I don’t know if this helps you or not but if you shoot a higher caliber than that, I’d just contact FLIR like I did. It takes about 4 days before they answer you.
