## Customer Reviews

### ⭐⭐⭐⭐⭐ Great optic for $100.
*by B***Y 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.

### ⭐⭐⭐⭐⭐ not every long gun requires a military grade optic
*by S***D on April 9, 2023*

if i was going to 'war' i would get a military grade optic like aimpoint or trijicon or eotech.but, since i'm not going to war i don't require that grade of optic.now, just to be clear, that does not mean i want to use some 'airsoft quality' optic (that one can find so easily everywhere) that breaks the third time you use it.so, I was looking for a 'quality' (relatively speaking) basic green dot from a recognized brand for a long gun.like most people looking for such an item i have viewed many videos, ready many reviews and blogs, etc.in all of my research the Sig MSR came up again and again as a good solid optic at what most say is an unbelievably low price. I found few true complaints about the functioning and durability of the optic so i bought it - and I am happy that i did.solidly built; nice bright dot.some mention the difficulty of opening and closing the covers. but, since i intend to run this optic with them on (since you can see through them) that is not an issue for me.the only other concern some say is that it is difficult to turn the brightness dial. I find it usable and actually like it (though my guess is that it might loosen up a bit over time). The 'trick' to using it is to do one 'click' of the dial at a time - not several at a time.initial reaction is that the reviews are correct - its a well built solid optic.recommended.i will update this review if anything changes.

### ⭐⭐⭐⭐⭐ Good quality optic
*by T***K on March 29, 2020*

Yes the MSR does not have all the features of the Romeo5 red dot like the extra low mount, motion activation, longer battery life, and the use of a more common battery. However where the MSR red dot shines is in its simplicity. It is very easy to install with the tool provided and has very clear glass for a red dot. MSR has two more bringhtness settings than the Romeo5 and because of the brightness adjustment knob you know what setting you are on at all times. The MSR has attached see through lens covers that stay attached to the red dot which is a plus in my opinion. The CR1632 battery used in the MSR is not as common as the CR2032 in the Romeo5, but is not impossible to find and not very expensive. I also found that the red dot did turn off infrequently when firing, but after a closer inspection this was caused by the batter cap not being tightened down properly (which was user error). After everthing was tightened the MSR has functioned flawlessly and is still going strong. Overall the MSR is a good simple red dot for the money and is defently worth a look.
