The TCQ-1 shows a guy holding a rifle over a wall, but the web site is not working well and there is no more info on this scope from this site.
I'm looking for this scope.
I have sent requests for more info but have not had any responses yet.
If anyone has any info on this please chime in.

Well it's a chinese company. I highly doubt you'll be able to obtain one.

It's safer to get a barrel that shoots around corners.

I’ve seen something like that on a Russian website years ago too. Not going to go looking but if you search for “zone of defeat” you might find whatever is still on the web. Eotech had an angled viewfinder that allowed you to view your red dot sight picture from the side so you could stay behind cover.

Something similar to this?

There are a couple Russian models that do that but they both have AK side rail specific mounts. They work very well though, I have both and am really impressed (if you really need to shoot around corners)

Eye piece can rotate left or right on both optics

The Russian system was definitely a fiber setup that they cqb demo’d on a revolver and rifle. It was on a Russian website that was written in bad English. The eotech-ish device was an angled prism viewfinder that flipped to the side like the magnifier. I saw it on a website closing them out for a few hundred dollars years ago. Its been a long time and I could be mis-remembering but I’m sure sure about the Russian one. The hide site posted above is kind of similar in size and function to what I remember but more complex and doesn’t flip aside when not needed.
