I have a 5-25x58 as well. Went with the RDP Mil. The center section of the reticle is extremely fine, which allows hits on small targets or extended range. The subtentions take some getting used to. The reticle offers the fine cross hair of a target scope with the FFP range and holdover estimation of a tactical scope. I love it
I have the MIL MPR in my 5-25. But if I were ordering new today (I ordered mine in 2010), I would go with the MIL-RDP for the fine line in the center. All superb reticles.
Gen2 XR looks interesting. Sort of a simplified Horus.
I would go with the Gen2xr or RDP mil... Gen2xr would be my first choice. The Gen2xr has a very nice thin crosshair that doesnt cover up small targets at long range. The layout of the gen2xr is nice for holds.
