That button is almost 1/2"diameter, I think it would be hard to fit. What would be cool is getting a hold of the switch used in the orion v2.1
Okay that was funny. I thought at first that was your original cap but I see you machined a completely new cap.
And also I was thinking of maybe adding this switch to my #20 (I know, I cant leave well enough alone).

What do you folks think. I think I can make it work with a little more modding.
