I would like to see one. I like the circle-dot in my field of view. The circle on the Vulcan is not visible if on target. It’s all about personal preference though. I really like that 8” circle at 25yards on the standard circle or circle dot.
If I was going to spend more money in a RMR footprint, I’d go with a 508T. I like the profile better, it is a much stronger case, and the lettering is more subdued.
The Vulcan is a good reticle to start out with too.
I agree with the 508T. If I didn't have a good supplier of used RMR's That's what I'd be running. I like the squared body of the 508T v's the curve of the 507c.
