I have a couple of these EPL4 4-16x44 MIL. The center dot is very small (to me), the illuminated reticle is on the small side. The elevation turret 3 set screws come loose after a few shots and when you go to make an adjustment no clicks just spins. Emailed Arken, was told to get some Vibra-tite thread locker, so far it works. Aside from the above it's clear, seems to track ok and eye relief is good.
