If it has to be a regular plex then NF SHV 3-10 is the closest. They dial well if you don't mind removing the turret cap.

The LRHS 3-12 is a solid option on a FFP with dial but it isn't a plain plex. It's a very "huntable" FFP reticle from near to far. It is much more of a "dialing" scope.

I sighted in a S&B Klassic 3-12 yesterday evening. Adjustments were perfect on sight in. Very nice scope. I've had good results from several Klassic 6x42's and I expect the same from the 3-12. S&B doesn't have a plex but they have some plainer reticles like the A7. I really like their P3 (basic mil-dot) reticle...not to busy, 4 posts, wind/elevation holds. I believe the current production models of the Klassic 3-12 all come with FFP reticles....different people may prefer or not prefer that. I really like it with the P3 reticle.
