Everyone say's they're confident it will hold up. Hell, my UTCxii had to go back for a dead pixel refresh ... thanks to the SCAR17. I know of another dude who had to send his back too, same reason, but lots more dead pixels. Trijicon would blabber about how it was recoil rated, but they'd never confirm it's gtg on a 17s. When they start talking 1 year warranty, you'd better figure out if it'll work on it pretty damn quick because once you're out of warranty, you're SOL.
I know another gent on here dusted a PVS-30, non refurb... sent it back for warranty work. They all claim to be recoil rated, and no doubt, the 30 is probably the sturdiest, but it still fails. I won't even try my 24LR on a SCAR. Perhaps on an AR10, but for now, I'll stick to the AR15s and bolt guns with that guy.
My atacr 8x held up on the 17, but I wasn't blasting it with thousands of rounds. I'd imagine you're ZCO will be fine, but time will tell.
