W/O going into this again in minute detail. Sent my stock SAI M1A back for an occasional failure of bolt going to battery. While it was there, I asked SAI to install NM sights, unitize gas system and do a trigger job. SAI replaced the receiver, the barrel, extractor,spring's,etc.as well as requested extra's. The rifle is now much less accurate than when original, plus it now has the problem of occasional failure to eject 165 gr. loads. Seems to function fine though on surplus NATO 147gr. Groups at 200 yards with fixed 6x42 scope are like 8 inches. Flyer's abound! NM. Irons, sighted at 100 yd. are miserable. Doesn't matter the ammo. Radway grn. Port.,or hand loaded 165 gr. Sierra BT. Lest some of you might think it's me, I just scored 3rd in a high power off-hand rifle match with a pre 64, Win. featherweight in 30.06. Need advice as I'm sick of spending any more time or $ on this rifle. Thanks in advance for any suggestion's forum members may have.
