Madcratebuilder- thanks for all the help, and I did remove the set screws and check the fit against the receiver. All looks good to me. It's just when I look through the sight channel, it appears that the mount is slightly sitting to the left. First I thought it might just be that my rear sight was adjusted over, but it is centered on the tick marks. Anyways, I'm not really that worried about it. I'll be sighting in in a few hours and I really doubt it will be an issue.
I'll also be looking into a cheekrest, so any input in that area would be appreciated.
On another note, has anyone ever tapped the front of the receiver to attach a scope mount on a m14/ m1a. This looked like it is the only improvement that could possibly be made to the sadlak style mount. May be completely unnecessary, but I was just curious.
