I have one in Scorpion Se full power format. I disagree with the easy to work on part. I've opened these up and done significant work on their internals and they're well put together and very high quality, but not super trivial to take apart. But the build quality is superb, as good as any other hand built European gun. The magazines are great, the magazine release is slick, the bolt is snickety smoother silk, makes those rich warm sounds when operating all parts of it. I usually like wood but I do have the synthetic stock and it's definitely the best synthetic stock I've seen, and I've seen them all. It's super heavy and solid, feels like the stocks on my big bore real tactical firearms. It is fairly heavy though, but mine's the full length barrel, cylinder, and solid stock. I'm actually going to detune it with a regulator at some point, because it's more powerful than I need, and quite loud. A large Donny does a good job on it, and right now it wears an Astille with one extra extension and it's not silent, but quite quiet. There's little to no ping, and the firing cycle is very nice.
I have more high-end air rifles than I can remember, and I would say this one is tied for my favorite, alongside my air arms s400 and s510.
interestingly the single shot system on these is amazing, it's not just a tray but a hinged flip open loader, that's milled from aluminum, and is ultra high quality. Nothing like any other single loader system. Though the loader cost 50 bucks, as soon as I tried one I instantly ordered one.
