I would say a red dot for Coyote out past 100 yds is not a good choice (dot size issue and the size of a coyote). Magnifier makes it awkward setup.
Illuminate scope would be better.
Also, inexpensive red dots to fail a lot. Even my EoTech dimmed out. The good news is while it was well outside warranty they fixed it for nothing and sent it back in their special case that I did not get when I bought it originally.
