A cheap option but not a good one - Holosun OPMOD AEMS 1x0.87x1.1in Reflex Red Dot Sight

The mount is garbage and you will need to buy a scalarworks or something decent to ensure a proper mount. The optic is not durable and has plastic covers front and back that scratch instantly causing issues with the view. I have concerns if it could survive a drop test. Field of view is good for a mailbox type optic. Though its enclosed glare in full sun is an issue. I see artifacts of the emitter when full sun hits the back window. Pros are its cheap, but I wish I had just saved up a few hundred more to get something that I would not be thinking of replacing after a couple months.
