I sent my new Loaded back to Springfield due to the sight moving under recoil, FTE, and shooting about 3 inches low. After a month the gun was back with a new rear Novak, shorter front post, tuned extractor, and stoned breech face. Did they do a good job? YES! The gun shoots perfectly now. Hole in hole at 15 yards and no more sight movement. I wish it was this way out of the box but they did make it right. My only gripe was they did not reimburse me for the $64 shipping charge. I still may buy that M1A from them after all.
