I have a 4.0 Tactical gen 1 HOST cut gun and have had both optics mounted to the gun. I Originally purchased the DPP because I liked the bigger window and top loading battery. What I didn’t like about the DPP was the center mounted activation button. Your finger obscures the dot as you are trying to change brightness levels. You also need to scroll all the way up or all the way down to get to the setting you want. Also, the taller footprint obscured the iron sights.
The SRO was recently released so I decided to give it a try. It has a bigger window than the RMR, and also has a top loading battery. There are two adjustment buttons, up and down, and they are located on the sides. The SRO is shorter than the DPP, so the irons aren’t obscured.
Both are great sights, but I prefer the ergonomics of the SRO on my gun. I should mention that this is for a non-duty weapon. According to reviews, the SRO is a target sight and not as durable as the RMR which is considered a combat sight. I figure with all the contracts that the DPP is getting, it’s probably also rated as a combat sight.
