From the picture you supply, that's not adjustable. A lot of those regs are fixed by a specific spring set inside and do not have an external adjustment. They were designed to be simple and reliable in that fashion.
Now.. you CAN buy another reg that will fit the tank. You can find many online, even eBay, but pay close attention to what pressure range the reg will handle, as well as the output pressure. You can find others that are fixed, but different output pressure, or an adjustable one (which will likely be more expensive) if you're trying to get it lower than it normally is.
The user guide for that reg will tell you the expected output pressure. If it's not performing within those specs, you should either take it to a reputable airsmith or in most cases you can send it in to Crossfire and if it's a physical (warranty) problem they may very well fix it for free. If it's been a while they may tell you up front that it'll be $xxx for a rebuild but afterwards it should be like new and ready to rock and roll for a long time.
As a master airsmith myself. I have various spring kits for some of these regs that the manufacturer allows to have done outside the factory, so you may check with an airsmith in your area and compare prices with them versus sending it in, but make sure the airsmith is dependable and will guarantee the initial repair, otherwise I'd play it safe and send it to the manufacturer for the max in confidence.
Good luck! Play hard, play safe, play with honor! 8^)
