Still looking for custom rail

You could also go with the Ivey Shooting 50 mil adjustable 1 piece scope mount. I just got mine. you can get the170 MOA version. I have mine on a 30 moa rail and with my scope zeroed I have 72.4 mils of travel. So I can now dial past were my .338lm will shoot.

Don't believe Ivey has made the 50 for years now. I still have a couple of sets. It will not work for my current problem which is getting more MOA on an EXTERNAL mount scope.
 
Mirage ULR made me a very nice 50 MOA rail that gets me out to 2500 yds with my lapua improved & still gives me a 100 yd zero. Give them a call and see what they can do for you.
