BCM extractor upgrade kit and the Alexander Arms Overwatch - Didn't work out for me..

@LRRPF52 and Bill -

Thanks for that meaningful insight, you are both spot on. Information that I wish I had armed myself with prior to attempting the BCM extractor upgrade.

Thus far (30 rounds) the DPMS 5.56 replacement spring and insert have not caused a problem with function.
