No problem. I had a bit of a dither lapping the Warne Rings because they are vertically split but other than that, no issues.
Just makes sure that the underside of the EGW rail mates to the top of the receiver properly. I did make sure there was no evidence of any burrs on the underside and confirmed the underside radius on the EGW matched the contour of the receiver top (mine is rounded). I used radius gages. I torqued the mounting screws ro 32 inch pounds with blue threadlocker and with the bolt out, made sure there was no protrusion from the mounting screws into the receiver itself. There wasn't.
You really only need about 1-1/2 full threads engaged male and female.
Have fun....
