Thanks Mike!
This is perfect! Being the owner of an XM177 (bought and built from kit) and having experienced ALL the problems most of us have had getting it to work properly, this film is invaluable.
Mark has listed (as well as a lot of you) posts explaining how to tune these but I had no idea what the 'Auto Sear' was!
This film shows it and how it all works.
Great, more like this would be really worth having.
