I am going to be putting a red dot on a 22 rifle which is short and compact and was needing input on the best red dot for $250 or less. This is a casual use rifle that needs to be somewhat reliable, so I am excluding the $39 red dots. I am looking for something plausibly dependable in the long term. There are new models all the time and so I though I would seek advice on whats out there. Really my only criteria are 3 moa or smaller dot and ability to mount low, built for real not for toy airgun.
