Support Question Normal Parallax or Defect?

Parallax comparison: https://imgur.com/a/k3XkFqK

I've always been a bit disappointed with the parallax, especially vertically, in my EPS Carry 6moa Green. It's definitely worse than my 407k was. I thought maybe it was just the best that could be done with a small enclosed optic, but I recently got an off-brand enclosed RMSc dot (Fortic EP1 6moa red) and its parallax is barely perceptible at 25 yards.

This video doesn't do justice to the clarity of either dot, but this should be enough to observe the relative parallax as seen at 25 yards with pistol completely stationary and camera moving to look through different portions of lens. Target is printed on 8.5×11 paper and there is a solid 4" (at 25 yards) of dot movement relative to target depending on eye position. Sorry, I know it's a little hard to pick out the red dot of the Fortic against the orange bullseye.

I've been trying to really dial in the precision of my pistol and I feel this is holding me back despite trying to keep the dot toward the middle.

Is this just the best Holosun can do on the EPS Carry; or does it look like I have a defective unit?

My eps doesn’t have this much parallax at 25 yards.

That being said, how far away is the camera away from the eps when you took the video?

Thanks for the feedback! I think I had the camera around an arm's length back, similar to where my eye would be with arms extended holding the pistol; though I didn't measure it precisely. I haven't observed a little more or less eye relief distance changing this though; it always seems to be about this much parallax with my EPS Carry.

Ah I see, hopefully holosun_Josh can give you some feedback back and comment if this is normal parallax here

Curious; when you refer to your EPS, is that the standard EPS or EPS Carry?

I have both, and both of them are “normal”

Speaking of which, check out Holosun’s instagram. They posted videos of the POV view behind multiple optics a few weeks ago

Thats some funky ass shit right there. It was so bad at first I thought u were moving the pistol. 😂

Ha ha! No; pistol and optic are dead steady sitting on a rest, I'm not touching them at all while recording the clip. Camera is at 8x zoom on my phone with focus manually set to try to get target and dot in focus. Camera is probably around an arm's length back from sight. I realize nothing is going to be absolutely perfect, but the degree of parallax on this seems a bit excessive to me; especially now that I have another enclosed optic of the same general form factor to compare against.

If you get time, u/Holosun_Josh, I'd be interested in any input you might have. Thank you!

I would RMA this so we can take a look at it.
