Excellent mid price optic to go with romeo5 red dot - Holosun HM3X 3x Red Dot Sight Magnifier

Only difficulty was rotating it on the mount so that it would flip “away” to the left side. They include a torx tool for disassembly but it not up to the task. Needed a real torx key to break seal on blue thread locker. That said, the magnifier aligned with my romeo5 right out of the box perfectly. Very clear glass and excellent eye relief. Haven’t tried it beyond 150 yds but works great so far. My only complaint is the bikini style lense covers. Wish all optics would come with flip up covers. The flip detent seems solid. No movement after several hundred rounds.
