My issue was the parallax issue Arken has become known for with many of their optics.
@vincent7 had a similar experience with his optic.
I contacted Arken via email and phone, got a reply 2 days later by phone.
The guy went through the same problem solving process that I had already tried.
Then he told me that some reticle movement is in every optic, which is absolutely untrue.
I was getting like 2-3in shifts at 300yds...
Many cheaper optics have performed better than Arken in this category.
So when I wanted a return label started, it never happened...
I waited over a week, with no other response from Arken, as did another Hide member.
I returned it to Venture Firearms, and Joseph was beyond helpful in resolving this.
Arken has a ways to go to earn my business, as I am questioning their quality control processes now...
