Clearly the pad is an issue, as well as some other things. The 4k range was in my head as well.

On the buttpad, would they all have had skeleton plates? Wasn't there an option for a pad from the factory? Clearly not this pad of course. I am just trying to justify why someone would hack off a skeleton plate to replace with a pad.

And the more I look at other images of DHEs, the more bothered I am by the rib.
