I need to change out the NM rear sights on mine to standard sights and maybe widen the front a touch. Old eyes and that small peep on NM sights don't go together very well. I had my M1A up the hill to a guy by the name of Al Ewing who stoned the trigger and it is much smoother and trips right at 4.5 lbs, the weight minimum for matches. Al was a winner of a bunch of trophies at Camp Perry when he was in the Army Reserve and had a great little gunsmithing business going. He could talk all day about the M14/M1A. He passed a couple of years ago, I sure hope he was able to pass his knowledge to someone.
