Meh, thats all I really have to say for this scope, it was handed to me during a game from a friend, which he had no use for seeing how he could barely see it during broad daylight, which tells you that much already. There only two ways to adjust this, one being the knob on the right, be careful too over unscrew it or the screw that holds it in place will fall off and you'll need to glue it in place and deal with an annoying rattle. The second is the knob on the bottom rear area of the sight which is your "elevation" The Ruby coat on the lenses is a nice touch though. For the price I'd use this for an LPEG or something along those lines. The fact this the lenses are plastic does mean it wont shatter compared to those ARMA scopes which can and will if hit directly. It's a basic red dot with only one setting and a Off/On setting. Weaponblender does know how to make a product look appealing though. The whole thing is plastic so the plastic, especially the mounts, are prone to breaking if forced.
Very solid and very light to and it goes good on most CQB M4
