For those of you who want the abridged addition,

The Anderson had 200 rounds through it and bolt had already stretched at the pivot pin hole to the point it was about 300 rounds from failure.

After 7000 rounds the tolerances on the DD were still tight, and the biggest issue was some slight pitting on the end of the firing pin.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.

You cannot over estimate the unimportance of nearly everything. John Maxwell
