Macro Line fittings in 90 degree and straight that will work with standard Macroline to connect the regulators to the asa bottomlines on paintball markers. These are commonly used on Automags and Autocockers as well as many pump paintguns.

I do not recommend using macroline on paintguns that you plan on running co2 in since the macro will commonly blow if the pressure spikes. Also check what your macro is rated.
