I sent an email on 8/14 to info@ArkenOpticsUSA.com reporting that my new SH4 was stuck at 7x magnification. I have not yet received a reply. This issue is the first I have had and think this is my 5th Arken scope purchase.
How do I return the scope for replacement?

Some of the Arken magnification rings are pretty stiff to begin with. Go ahead and give it a good twisting to see if it loosens up. I have only had 1 of my SH4's be super stiff, but it got way better after working with it for a bit. Give it a try!
