I went with the Sage EBR stock. I couldn't be happier with it. Optics mount easily, stock adjs are solid and repeatable. Group size was reduced by about one half inch with SA ammo. Getting the rifle fitted into the stock took some time and care but anyone who can correctly take care of a M1a should be able to do the job. The rifle fits into the stock TIGHTLY, contacting it in two places only, the new bolted in barrel block/op rod guide and the receiver. Recoil is easier to handle with the inline stock and weight shift slightly forward. You can watch bowling pins fall at 200 yards through your scope. Nice set up. Glad I spent the money.
