Back Bottle Valve Body for the Nelspotgg-vb-bb
Back bottle valve body for Nelspot and compatible Nelson based markers.
2 air holes for higher flow.
Adjustable pin de-presser for air tank (must loctite set screw after anodizing or before use).
Inside bored out for higher volume. (major ID is bigger than minor of threads)
Originally done for Co2 expansion but will work to help run lower pressure and have a better consistency.
