I am using Arken Optics FFP rifle scope SH-4 4-14X44 with AZS Zero Stop.

I've only seen the Arken on a few posts so far, and only in 2 of them, over on snipershide, do the posters have more than a very few posts or history.
Arken has no warranty info on their site, and the dude who is supposed to be a vendor on snipershide said, iirc, 'pm me' for info. Not confidence inspiring.
They look like the same tube/body as primary arms' 4-14, which I think at last count, 5 different vendors were using for their own name branding, produced by the same chinese vendor.
Likewise, nobody has posted a box or return to zero test...of course, one of the guys who is a vendor has said he's done a box test, but, well, even though pics of that kind of thing would be easy to fake, it's still not confidence inspiring.
And when they're ~$75 more than either Primary Arms (known company, well known 3 year warranty), or a used vortex or athlon (lifetime warranties on both), well, although they look nice I'll pass until they're a truly known quantity.
