The Warne rings are fine, as far as the quality goes. I have a couple of sets.
It's hard for us to know if they'll work, since we don't know what scope you have. It will depend on the size of the scope/tube, whether or not those rings will raise it up enough so that it doesn't hit the handguards. I can almost quaranty you they won't be high enough for any BUIS, though. Even the high Warne rings aren't that high. As you mentioned *not* using iron sights, this shouldn't be a problem either (I just mentioned it for fyi down the road).
Eye relief shouldn't be a problem, just don't expect to be able to go nose to charging handle unless you opt for a mounting solution that moves the scope forward. That never bothered me, I don't ming having a cheek weld that puts my face away from the charging handle. Obviously, this will vary with the amount of eye relief each particular scope needs.
If the Warne rings don't work, you can try to sell them in the EE.
A lot of folks around here like the ARMS rings, or the LaRue mounts. That can get pricy, though...the ARMS mounts are around $100, and the LaRue is double that. Both of these options provide a nice solid mount, that are easy to remove should you need to. You might find down the road that you want a red dot/scope set up for that rifle, and the throw lever type mounts come in very handy for that.
