    Inaccurate parallax calibration EP5

    My EP5 5/25 works well, but the parallax settings are completely out to lunch. For example, at a 1000 yard target a careful parallax adjustment (not merely sharp focus) shows about 175 yards on the scale. Anyone else seeing this or is mine defective??? Thanks!

    Arken Ring Lugs Too Wide For Non-Pic Rails

    I got my second Arken SH4 and cantilever mount. I has previously ordered a 20 moa rail for my Gustav 6.5X55 Swede. I found that the lugs on the Arken mounts are too wide to fit the slots on the Weaver rail. I searched for a Pic rail for the same rifle and can not find one I think will work. I looked

    Mounting the 57mm Objective to a Daniel Defense DD5 V4.

    I ordered the medium rings. Thinking about it, now I’m wondering if the 57mm Objective will clear the pic rail with the medium rings. Do I need the high rings to give the scope proper room and clearance?

    Waterproof? Shockproof?

    Wondering if the new EP5 is waterproof and shockproof? What caliber is it rated to? Have heard some reports that would suggest hunting with it in the rain would be a bad idea.

    Any independent review of EP5??

    Has anybody on You Tube or elsewhere put their hands on an EP5 and given a comparison to the SH4Gen2? I would have expected Rex, Cyclops, or one of the other popular people to have published something...????
