The Nov. 2009 issue of Shooting Times' cover article was titled "Scope your M1A!"(shining the light on M1A optic mounts).
It was writen by Joseph von Benedikt. It is a very good study of your problem. If you can not locate it let me know and I will LOAN you my copy.

I have the Springfield Armory one piece mount for my National Match M1-A and it is a very solid mount. It's very similar to this one.
This is my rifle with a 6x-24x Burris scope.

i also use a sa mount. i think it is a gen2 or 3. i didnt have much luck either.......
Like earlier, I have found not all receiver specs are the same. Sadlak makes the best I have seen, followed by Smith Enterprises. They are pricey, but everything for an M1A is. Sadlaks website advertises how to measure your receiver. They state some hand fitting maybe required, or you can mail it to them to have it fitted. Also the accuracy issues found in the M1A, are mainly because the M1A is NOT the M14. The M14 was made from bar stock, not forged. Also the M14 has a rear lug. For years there have been complaints about the quality of parts and whether or not Springfield uses USGI or knock-offs. Springfield Armory is not the same company as the M14 stamped Springfield. They use the folk lore and similar name to sell M1As. I found this out the way most do. My dad talked about how great the M14 was in Vietnam and how he didn't like the M16. He would talk about shooting long range with irons, then with a scope. With all do respect, most vets I have heard talk about Vietnam, talk about the M14 like it was the right hand of God, and the enemy didn't have a weapon to give them a fair chance against it. I used the M16/M4 weapons when I was in and we butted heads over the reliability. I have an M1A. Think I will sell it and buy a Grendel. After all, were talking 60 year old technology shooting a 60 year old bullet. It's sad the US has been stuck on the .30 caliber thing for years. The Europeans have used 6.5s since WWII with success. I am glad they are catching on over here, especially with the bench-rest guys. There's my .02 cents.
I still have this M1A mount if anyone wants it. I need the money to continue feeding my Grendel habit ...
