Most Helpful Positive Review Underrated Optic
As the owner of a broad range of red dot optics, I've spent a lot of time comparing the SIS to optics made by Trijicon, EOTech, and Sig/Holosun. The single most important factor for this optic over others is the auto-brightness. Compared to anything else I've ever seen, on all optics made by Shiel...

Most Helpful Negative Review Spend your money elsewhere
I had this on my KSG12, only shooting slugs for a couple hundred rounds. It held zero throughout the multiple sessions, had easy adjustments and the reticle selection is nice. Especially for shotguns. The multiple risers you can choose from also adds versatility and comfort. HOWEVER, when I went to...

Update to "Underrated Optic" Review

by Curt, from TX, United States Written on September 8, 2021
As an update to my prior review, I would like to add a few negative points.

NOT RECOMMENDED FOR DUTY USE OR SELF DEFENSE PURPOSES

This is still a recommended optic, but it can only be recommended as a durable substitute for training and range use optics. It is rather durable and is rated for a lot of recoil, but it is hard to trust that it will not have its brightness or windage adjusted inadvertently. For range and training use, it simply isn't worth spending any more money than the various Sig and Holosun options for far less money.

I am skeptical that the SAS is employing these for any reason whatsoever. For use with night vision, there doesn't appear to be any optic on the market even remotely as good as the EOTech EXPS3.

1. The auto brightness that I like so much about this optic compared to other optics is no longer relevant to my needs. It simply isn't bright enough to justify using anything other than manual brightness, and the same is true for all other optics. As well as the Shield Sights optics handle adjustments for lighting conditions, there are simply none that adequately adjust for bright light situations. Unless all engagements with this optic (or, for that matter, any other optic) are in low light conditions, it will never be bright enough. See target discrimination with a WML: Use of a flashlight to positively identify any potential targets so you don't fire on an innocent such as a family or first responder. That being said, the optic still me...
