The standard duplex in Trijicon Accupoint and Huron 3-9s is pretty thick in the sidebars and the center section is small, 8-8.6 MOA, making them stand out well. Some German 4s suffer from the same issue as many duplexes, a wide center gap that leaves you aiming with essentially a pretty fine crosshair.
Amazon has the reticle details on the Trijicon scopes included with the descriptions, easier to get to than on Trijicon’s site.
Another good one is Tract’s T-Plex.
