This is the RDS that I have on my C39. It is very well made. It doesn't have the fancy push button zero adjusting but it also doesn't cost $500+. It has 12 brightness settings, which are controlled by the + - buttons on top of it. I find settings 5 and 6 to be perfect for day or night shooting. It is compatible with night vision optics on settings 1 and 2. Zeroing is done by use of the two screws contained under the caps as per usual. What looks like a large knob is the battery compartment. I've used sights from both Eotech and Aimpoint and I actually like this one better.
