I have spoken to a couple of retailers that have stopped carrying them due to quality control issues.

I doubt it.

People here in Utah seem to really like them. I think for the cost, they’re good optics.

they were until they got their foot in the door.
then everything stepped back and the price went up.
I went from buying nothing but and being a fan boy to a skeptic real quick.

it didn't help their cause [in my eyes] any after I stood there and went through two different tables full of them opening and trying every scope there [for 4+ hours] then walking out empty handed.
too bad too, they were marked a very good price, and I already had examples of the scopes on both tables.

Their low-end Crossfire line is nothing to shout about and now I see they have added Sonora and Copperhead below that level. I've had good service from a couple of Diamondbacks.

Can't speak for new ones. I bought 3 of the fixed 6x when they were $50 and a 3-7 crossfire 2. They are on range guns, they work.
