Zero stars - Delta V Gen 2 3MR AR Trigger

Right of of the box, following the instructions i realized very quickly the set screw was unbelievably tightand wouldnt adjust down. Backing the set screw out to inspect and change out spring i noticed the set screws threads where rolled, looking into the threaded hole i could see the threads in the hammer had been flatted/ damaged. So trigger pack was trashed before it even left the manufacturer. I do not believe it is fixable with as bad as the threads have been damaged.

Called customer service, the help they offered is appreciated but i do not believe there is any way to fix threads that have basically been removed.

In the end this trigger is basically trash and unusable right out of the box before it ever got installed.
