Re: USO ERGO on a SN-3
Not necessary at all with 10x and 200 yards.
If you really want to be thorough, you can request that USO set the parallax on your fixed parallax scope to 200 yards.

If all your shooting is really going to be at 200 yds then that would be the thing to do. Unless you're shooting for the absolute smallest groups possible (eg Benchrest, F-class, etc) in which case you'd still want an ERGO to fine tune. But I doubt that's your situation since since you're looking at the 1.8-10x. ERGO's sell faster on the used market than fixed, but I'm not sure they pay for themselves when they do.

Re: USO ERGO on a SN-3
Would you need a side focus or ERGO for 1000 or less with a 10x?
Thanks,

Actually the diopter adjustment on your ocular is for achieving focus. The parallax adjustment puts the image and the reticle on the same plane so that you don't have issues where the position of the reticle is relative/dependent on the location of your eye to the center of the image.
When this is achieved, coincidentally, the image should also be in focus because it is on the same plane as the reticle (which you focused using the diopter adjustment.)

Re: USO ERGO on a SN-3
Bear in mind that you can upgrade your fixed parallax to ERGO later for the flat cost of the ERGO in the original build,
(I think it's ~ $200)
so really all you would lose is some time...

I know, Ratbert, I just didn't want to write all that!
