The new Hera CQS is a new reflex sight which features a foldable lens. The lens can fold down out of the way. Pressing the release latch flips the lens back into position (much like the current generation of BUIS).
This is a clever design. It would make a compelling alternative to the Docter Optic red dot sights which are sometimes used as backup or close quarters sights alongside another sight.
The CQS sight is made of aluminum. It runs off two volt lithium batteries and has a 4 MOA dot.
