Just got back from the range shooting my "new" M1a for the first time. I used some "ZOI" ammo that was made in Turkey and sold on sale at WallMart for $9.97 for 20. I also shot handloads of 42gr. 4895 w/ 150 gr. GI pulled bullets. I didn't expect a lot this first time. Was I surprised. The gun shot all 1" groups and a few 3/4" groups. I was impressed. The only issue I have is the elevation needed 24 up clicks to zero it. I didn't like the thin (.062) N.M. front sight and will replace it with a std. thickness sight and probably cut it down some. Is it common to need that much elevation?
The rifle needs it's gas cylinder shimmed as the lock nut bottoms at 180 degrees off. However, as long as it shoots this good, I won't touch a thing, except the front sight.
