Great optic for $100.
By Bkinsey on Reviewed in the United States on September 14, 2021
Hard to complain about a $100 optic that does exactly what it should and fits the purpose I intended perfectly (Roni MCK/19x set up). As noted, this is a green dot sight. The MSR is very well made and appears to be very durable. Others have complained about the flip up lens covers and while they are a bit difficult to close it seems to be a nuance in technique rather than a design flaw. They close fine if you apply downward/forward pressure on the lower portion of the cover. The green dot is crisp and brightness settings are ample for a variety of conditions. More than 4 at low light seems to produce a bit of an emitter glare but that’s no big deal. 6-8 in daytime seems best for my eyes (slight astigmatism). Control knob is slightly stiff but loosened up after a few setting changes. Not an issue. Sight mounted fine on the MCK rail and is an absolute co-witness with the Magpul MBUS. Glass is clear and crisp - even through the lens covers being down. Again, no issue there. Zero easily achieved and held after a session of over 100 rds. I have other SIG optics and the MSR holds true to the design, ease of use and visual appeal of the others I own. No complaints for a $100 optic on a range/home defense toy. Would highly recommend.

VERY DISAPPOINTED
By mike lewis on Reviewed in the United States on August 29, 2024
Purchased after watching many YouTube reviews. About the only good thing I can say is that the dot is sharp. The illumination control knob is so hard to turn that pliers were required to turn it the first time. It loosened up a little with use but is still ridiculous. There is absolutely no correlation (or consistency) between the windage/elevation clicks and the movement of the point of impact. One MOA per click is a joke. Sometimes 8 clicks won't move the POI at all, and the next time 2 clicks will move the POI 6 inches The best I could do on my measured 100-yard range was a decent group at about 8 o'clock and 4 inches. I gave up. The flip-up lens covers are going in the trash, if I don't send this thing back. They are so hard to open and close that they are almost useless. Tip: The included tool can be used to pry them open.
