Well, I finally took my new standard M1A to the range today. I'm not much for cold weather, so I had to settle for an indoor range. 25 yards isn't exactly a good way to benchmark a rifle's potential, but I've had this thing for about 3 weeks now, and it was time to break it in.
My serial number is 158xxx. Not "100 percent USGI" by any means. I fed it 1970's Spanish suplus 7.62 and it performed flawlessly. About the only problem I experienced was with a cheapo 5 round magazine not seating well. But, that's not a flaw of the gun or the ammo, and the 20 round magazines from Armalite had no problems at all.
The only REAL problem I experienced was that the elevation wouldn't stay zeroed. That was probably my fault, as (like an idiot), I decided to remove the screw on the elevation knob this morning just to see what it was for, and put it back on. I probably didn't put on tight enough, and after talking to the very friendly, and very helpful people at SA, I figure that's probably the source of the problem. I'll find out for sure when I head back next week.
All in all, I'm happy. I was almost scared off by reports (rumors) of SA's quality problems. It seems like I needed a higher number of clicks than I thought just to zero it in at 25 yards
Anyway, I just thought I'd add a big +1 in SA's favor. I know some consider the extra 500 bucks Fulton Armory and LRB charges to be worth it. I don't have any experience with those guys, but I can say that for 1200 bucks, I got a heck of a gun from Springfield.
