First Focal Plane. The nice thing about the USO scopes is that they are made to your specs. If you want more travel just order it with a 35mm or 40mm tube. They have metric or moa reticles. They have different types of elevation knows. One of the best features I think they have is the EREK elevation knob. It is full travel in two turns and it is really easy to read. You can go to www.usoptics.com
and configure a scope online and see all the options you can get with them.
The one I just orders for my 338 Lapua is the SN-3 T-pal 3-17. They are sending the scope body and all the external parts to my gunsmith so that when the gunsmith ceramic coats all the metal peices of the rifle he will coat the scope body as well. So all the metal on the rifle will match. This is the second scope I have bought from them and they are very easy to work with and are extreemly flexible. They are not cheap though. I think I will have about $3000 into the scope, anti-cant device and sunshade when I am all finish.
