Hornet also!
Dca is a pretty nice flush fit, but I am like you, I want an RBA for my p+10.
Edit: afterthought...
Bottom feeding hornet, is different. The bottom sits flush on the p+10. Bad thing is that it is bottom feeding. Some say that if you wire it through the bottom hole on a bottom feeder that it won't leak. I have no idea cause I haven't tried it. The middle is wider than the bottom, so it kind of has a slight V shape to it, very slight, but if you are ocd like me, you will notice it.
