I think this optic is brilliant. It looks exactly like the real Susat, even down to the red bits of paint on some of the screws. I love the attention to detail. The eye relief just like the real one is very short but I quite like that it replicates the real thing. My case for the optic was unfortunatly broken in transit, which is a shame because it's a lovely case but the optic was perfectly fine, as it's built like a tank. All in all, I'd say if you're looking for a decent replica of a Susat, you can't go wrong with this model.
