Great sight, many options - UTG Pro 4.2in ITA CQB Reflex Micro Red Dot Sight w/ Integral QD Mount

I have two of these sights both I use on 7.62x39 ARs. It is easy to zero with no tools and holds zero very well. The adjustable red/green dot is bright enough for day use and can be turned down for dimmer situations. The QD mount is secure and has many options for mounting, riser, no riser, cantilever forward, cantilever back, whatever suits you. Good value for the money.
