Decent red dot - Primary Arms SLx MD-25 Rotary Knob 25mm Microdot Red Dot Sight

I’ve got a wide range of red dot sights, from Trijicon MRO’s, Burris Prisms to Sig Romeo 4, 5 and 7. I would say this is above a Romeo 7, but below the MRO. It includes the risers for lower 1/3 and absolute cowitness, the dot is crisp (until the brightest setting) and it seems very well built. What I don’t like is there are no half turns for on/ off, like my Burris, and the knob for on/ off is extremely stiff. So stiff that it can’t be done while the weapon is raised and looking through the sight. I literally have to drop it, death grip twist it and raise the weapon. Other than that, clear glass, stays zeroed and seems like it will last a long time.
