eBay seller vortex scope?

[Frank_5.0]

If this is wrong section I apologize

eBay seller "optics*laser" has vortex scopes for pretty cheap compared to Turners. Diamondback 4-12x40 is $159 and a 3-9 is $199. Are these safe to say these are authentic vortex or fakes? Anyone buy from him before? Which would be better for a ruger American .308, thank you

Those prices don’t seem out of line to me.
