Yeah, looks to something really out of whack there for sure. My 10/22 (in an Archangel Marauder stock) will easily shoot into an inch @ 25 yds. with any ammo I shovel into it, so I'd expect your rifle to do at least as well.
It's common, in my experience, that where there are optics added, major accuracy issues are usually due to the optic or its mounts. Major issues with new rifles do occur, but not very often. Mounts, on the other hand, can deform noticeably with unequal torque, for example, throwing point of aim off. Inconsistencies usually indicate an insecure mount, allowing the optic to move from shot to shot. Of course, optics failures occur, too, occasionally, even in expensive brands. Loose internal parts can throw shots all over the map.
If you still have irons on it, I'd start there (to eliminate the rifle as the problem) if the optic & mounts check out.
