I tried out an Arken because of all the hype online. I picked up a used SH4 gen1 4-14 FFP mil. on snipershide.com.
Mounted it on an encore pro hunter 300wm.
Clicks were positive and audible. Tracking was spot on and repeatable. . Zero stops worked great and were easy to set. Glass was descent but not great. But then again it was a 350-400 scope.
Here is the bad in my case.
While doing load development and maybe 30-40 round in, I noticed some specks on an inside lens. Didn't effect the functionality but was an annoyance.
Contacted Arken and they promptly replaced it with the same model.
20 or so rounds later, same issue. Again it was replaced no questions asked with the same model.
Replacement scope, right out of the box had 2 VERY SMALL specs.
Again the company was more than willing to replace it no questions asked.
I have asked on snipershide.com if anyone had a similar problem and none have come forward in the affirmative.
The scope has since been replaced with the SH4 gen2 6-24x50.
I haven't had time to go shoot it yet but all the pluses of the first scope seem to be there. Glass seems a bit better. Of course i haven't checked the tracking as of yet.
We all hope whatever we buy never has a problem. But it is nice to know that if it should, you need not worry about this company backing their warranty.
