I actually just called Ruger's product service in NH and the lady on the phone said it would cost me $50 to have the existing trigger adjusted to 3.5 pounds is the lowest they will set it at. I've had my rifle since last August. At this time, they are not going to install the LC6 trigger on your MKII, maybe in about 180 days after the Hawkeye has been in production for a little while.
