I've shot quite a few. I wouldn't say I've used them extensively, but have at least a few hundred rounds through them on other folks guns.
They're price point optics intended to capitalize on the growing long range shooting sport. They have a nice feature set for tactical style long range competitions and good enough glass. There's a lot of variability in them. Optically some are much worse in similar conditions than others. They're fine for what they are, but they're nothing more than the price would leave you to believe.
In addition to incentivising reviewers financially I would guess they cherry pick their best scopes to give reviewers. I have no evidence to prove that, but it's pretty common to do that in just about every industry with variability in manufacturing.
They're definitely better than a the bottom of the barrel long range optics out there. To someone who's never used a high end scope they probably seem pretty great.
For someone on a tight budget they're not a terrible choice. Most lower mid range scopes, like the 800+ price point, will perform much better. Most $2000 scopes will be head and shoulders above any Arken sope I've seen, especially if you go used.
