Bought this December 2024, mounted once with vibra-tite a little residue left over and it couldn't co-witness (similar issue with another optic) so I removed it and put it back in it's box. It has never been on a gun that was fired, and it's new, just a little dusty.
Comes with origional box, all screws and plate and owners manual still in it's packaging. Pulled it out of the box and it worked no problem.
