I think Steve Watson has a Steyr tube on his HW? I wouldn't use the A+M alloy one, I serviced one fitted with this tube and was scared by how thin walled it is, with threads cut into that thin wall too!! Down right scary! I wont be touching another one! Alloy is alright if you stick to the thick wall tubes proven as dependable by the likes of FX and Anschutz etc, An alloy cylinder thinner walled than most steel tubes and with threads cut into it doesn't strike me as being safe!! Antonio Gentilini (Ginb) suffered life changing injuries from an exploding after market cylinder and was lucky to survive!
HFT, for people with only 2 buttucks!
