I just picked up an EP5 5-25x56 with Arkin rings and it will go on a .223 build for P-Dog hunting once I finish adding pillars and bedding the rifle.
In short, not much help as I need field use and time before making any judgement calls, but yes it's heavy at 39.2 oz. I do like the VPR reticle layout, the massive turrets, easy to read large numbers, and the simple zero stop that you can set without losing internal adjustments. However, the illumination is not daylight bright, but can see it early morning , evening and dark (doesn't wash out the image),
I also like the fact that Arkin puts the torque specs on their rings.
Yes. the EPL4 6-24x50 is a 30mm tube around 24.71 0z and EPL4 4-16X50 30mm tube around 24.11 oz, the reticles even though similar (VHR), it's much thicker as it was intended for hunting. I end up buying an S-Tac 4-20 because I like the mag range and more internal adjustment of the Tac.
