The CAD
Actual Build:

Gun hits count, don't forget!

You'll need to make up mounts for whatever gun you put this on.

This was made from 1/4" ABS, and I still have it here, somewhere...anybody wanna buy it?

You can see this is a workable firing platform- pretty much shields your face..
.mostly.
EDIT:ROFL- his site looks like mine:
