Thank you guys :)
Our experience with Bill began in August of 2010. The first time I called (and more than half the time I call, I get the man himself) Bill picked up the phone after 2 rings. At the time few people had heard of us, and I don't think Bill did either. I proceeded to explain that there seemed to be some confusion regarding the DMR trigger, some users had had to modify their selectors to fit, so I wanted to see what we could do to mitigate this, lest our customers should run into this issue.
Basically, it only started when Bob and Joe down the street and everyone else started making receivers that don't stick to specs.
When a receiver is out of spec, the detent/detent spring hole may not be drilled correctly (there may be other dimensional differences that could contribute to this) which wouldn't seat the selector square center, the selector's center flat section may be biased to the left or right, instead of dead center. The DMR's rear extension is wide, if the rear extension isn't in the flat section of the selector, it couldn't be pivoted as it would hit the round section instead.
Based on his recommendation, in PIP2 (product improvement program), we made the center flat section as wide as possible without jeopardizing the structural integrity of the selector. It's one of many modifications we did to ensure compatibility with either aftermarket or out of spec receivers, these changes usually go unnoticed by the users and just do their job quietly.

So we (Battle Arms, and our user base) have Bill to thank for his input, it's not everyday we get to talk to someone like Bill, who took his time to help out a company he never heard of :)
I hope I did not hijack this thread, we can't say enough good things about Bill's triggers and everyone that works at Geissele :)
