Best value - Bushnell AR Optics 3x Magnifier

I shopped around for the best and least expensive magnifier i could find. There are a lot of off brand magnifiers in this price range, undoubtedly all made in china, including this one. What stood out the most for me was that this Bushnell was the only one claiming it was nitrogen purged and fog proof. That's a must with even cheap optics for me.
I mounted this behind a bushnell AR optics first strike 2 and it works great. The red dot appeared off center through the magnifier at first but was easily brought into center with the magnifiers adjustment turrets. The flip to side mount is very simple, rugged, secure, and easy to use. I also have magpul polymer flip up sights. The rear sight fits just fine, folded under the magnifier. When the sights are deployed, theyre lower 1/3 cowitness with these two Bushnell optics.
Overall, a great, functional magnifier on a budget.
