I need a new level for my build. I was looking at a us optic rail mounted. Is there any draw backs to this type? or would I be better off with a ring mounted style? I'm limited to 34mm levels.
Thanks

I think that either style would work. Personal preference if you ask me. That said, I have the USO rail mounted, and it works just as you would think. One bonus is that you know that the rifle is level when mounting your scope to begin with.

I love my USO level but I'm happy that someone is asking the question.
 
Third secret option, run the bubble level in the back of the SPUHR ISMS. Out of the way, you know the rifle is level, and the wedge is the fastest way to level a scope going. And if you want to get technical it is both rail and tube mounted. only downside is the cost of the mount, however it's freakin worth it once you get everything mounted up.

im running an accuracy first and find the bubble to be more true. they also have LE/MIL pricing so i got mine for like 85 bucks.
 
The USO level is great and works just fine under a 34 or 35 mm tube. They used to have two different tightening knobs to choose from. If they still do get the shorter knob for the bigger tubes.

I also have a flatline mounted on another scope. The only real functional difference after the levels are set up and true are how you deploy it when shooting and where you look when looking to see if the rifle is level. I don't think you're going to find one method particularly better than the other.

I really would not over think the bubble choice. Go with what's in your budget and the mounting method you think you will prefer.
