If you haven't bought already, I REALLY endorse the Bassett Machine Mount. I use the High mount so I can co-witness my iron sights, a very important feature if needed quickly. Incidentally I have 2 M1A's and 4 Bassett mounts: 2 scopes and 2 eotechs. Swapping back and forth, maintaining the pairs for each rifle, I don't lose zero.
