Definitely professional quality. Snap on, snap off mount. Rugged and dependable, provides great cowitness with popup sights, on an AR anyway. I have one and it serves me well. There are various add on magnifiers if you want to go way out, but only two good ones that I can see. When it comes to optical sights, it doesn't pay to skimp. If you want a red dot, this is a #1 choice. I'd put it on the AR in a swap with the other one you have, which I assume is inferior, but that's just me.
