They blamed both the old triggers and the XMark.
First "oopsie" was a kid who was arguing with his brother, and loaded the rifle to "scare" him: The rifle "went off by itself".
Second "oopsie" was a "former Marine" who was "experienced with weapons" and took his LOADED RIFLE WITH A ROUND CHAMBERED AND SAFETY OFF out of a case and the rifle "went off by itself".
I stopped watching at that point.
There may well be a problem with the triggers; there's a bigger problem with some owners.
