Thanks Dave, Mike and Marcel. Marcel there are models just like it that are imported to Europe also, the Mrodair is imported here. The names of the Euro ones I think are Zasdar and Aceros. Not sure which one but one of them is in Spain (same exact gun). They are regulated and everything on them is adjustable as well, from what I've seem where even the tension on the valve spring is adjustable. The LDC & adaptor I got from Rocker1 here on the forum, it really works good. I'm averaging 16fpe with it the way it's adjusted.
