So I was reading up on rifles for home defense (Not urban or apartment) and the writer mentioned red dot sights as a superior alternative to open sights. I kinda got out of the shooting hobby about 15 years ago and picked it back up about a year ago, so red dot sights just weren't a thing back then. I love the open sights in my SKS, but would a red dot be better? (I have a taco T6 stock with rails on top) Or are red dot sights really only cool on certain rifles or really meant to be used with a scope. Are there any red dot sights that don't cost $500? Eotech seems to have the market cornered on crazy expensive ones.
