I have a Trijicon Accupoint 3x9 on a Springfield Gen3 mount, atop my M1A Scout.
I haven't had many issues with the Gen3, but at some point I will upgrade, probably a Sadlak, to get it a little lower.
My rifle is set up for quick target aquisition within 200-250m, which is where the Accupoint really excels. However, the obelisk style reticle makes it difficult to judge hold-over at extended ranges.
