Questions & Answers
Is there a lens cover available for this sight? Expert Answer

Not for this particular model.

by Ben, Gear Expert, February 16, 2021
What about people with an astigmatism? Expert Answer

Astigmatism will cause some dispersion of the reticle, the amount of which will depend on the severity of the astigmatism. Unfortunately there is no way to prevent this on any red dot sight.

Helpful Positive Review Great optic by Geezer, December 5, 2020
Great quality optic. It’s plenty bright enough for any daytime shooting I’ve done. Not a huge deal for me but mine did come with some scratches on one side. I was also a little worried about the batteries setup and location but zero problems so far.

Helpful Negative Review THE RDS to have, but useless outdoors by Moraa Koraa, Verified Owner, November 14, 2020
I bought this sight several months ago with very high expectations. The look, feel and feature set were perfect. Build quality is what I would expect from Steiner. Unfortunately the sight is too dim. I sent the original purchase back to Steiner (...
