If you plan to shoot commie steel case ammo, be sure to use a trigger with a strong hammer spring. A standard one will leave light primer strikes on the hard primers.
I have a Larue trigger with the included heavy spring and have no problems. I read elsewhere that there is much less wait time to get one now. They are down to $80.

Man charged in deadly New Hampshire highway crash had run-ins with the law in Texas
I have not seen anything about him being impaired at the time of the accident. I do not think the police would have let him return home to Mass. if they had any suspicion that he was impaired.

Regardless, the people were needlessly killed and he is the reason.
Here is a story about his arrest.

And you should seriously take the offer to meet up with mrraley to build your rifle. Anyone on the board would kill for that offer.
Maybe not funny, but it is sort of cool. It looks kind of like a fall shoot, except for the dresses and towels used as clothing and the total lack of firearm discipline. I do recall some tracers fired at night.
