Honestly, I would just go with Truglo. Optic. They are a known brand but don’t make the cheapest of products like other companies. That’s just my opinion. Bushnell has their products as well for great prices. It depends on what you consider inexpensive.

Douglas, Depends on how much you want to spend. There are many options by about every optic company. Here is a sub $30 red dot I use on my 870's. Never had a problem. Great reviews. --------- budsgunshop.com/product_info.php/products_id/60675/bsa+red+dot+w%2f5+moa+%26+black+finish

Douglas, I would recommend the Bushnell Trophy TRS-25 Red Dot Sight --- youtube.com/watch?v=8fzgFsNWo_8
