First up is a dual stage Matheson regulator. I bought it planning to do a build but ended up just running 2 needle valves. This will include a clippard mouse solenoid and Fabco Nv55 nv. You will need to buy the plumbing to the solenoid and also a power chord for it. I do have the pieces to either connect the nv to the solenoid or barbs to run them both inline. The regulator itself is in great condition and come with the cga320 stem and nut already installed. The working pressure is adjustable from 0-100 psi so you can run all forms of diffusers. Asking $120 shipped
You will not find a cheaper dual stage regulator!
Next up is a Atomic paintball co2 regulator. This is known as the best paintball regulator out there. I really loved running it but stopped using it when I set up my second tank. This has a set working pressure of 30psi so it will run anything out there. Will also include a 20oz. Paintball tank. $100 shipped
I do not have a bubble for either set up. What I have is a slew of diffusers. I have an atomic inline diffuser in 1/2" and 5/8" and also a small in tank version I got with the regulator. I can include one of these diffusers of your choice for free. I only have one of each so first come first serve on those.
