A bit hazy near the edges - Athlon Optics Cronus BTR Gen II UHD 4.5-29x56mm 34mm Tube Rifle Scopes, FFP

I've seen YouTube videos comparing this scope to some of the top scopes on the market, like the Vortex Razor HD Gen II. He went into detail comparing feature to feature. I was blown away. It is a nice scope with great magnification but I have a bit of blurr around the outer rim. I don't have that with my PST Gen II and I have 3 of those nor my NightForce NX8. Not sure if I has to do with the Ocular adjustment not being set correctly but hey if it's that finicky to set then idk. Maybe it's a lemon idk. Shoot accurate and repeatable it's on my custom 6.5PRC. OPTICSPLANET, let me know if I'm doing something wrong.
