Bagheera, nice. Looks to me like bullpup meets rifle. I'm looking forward to seeing it once you slap a purdy shell on it. FYI, the Qloader folks will replace pretty much any broken parts for you no questions asked.
MAGslinger, any idiot with a drill can do that six-hole mod - the catch is that it doesn't actually increase performance. Some early valves didn't align perfectly and the six-hole mod fudged that so they did, but it did very little then and it does nothing now that AGD threads the reg and valve so the holes line up.
