These are generic barrel models that can be used from marker to marker. The threading specifications I employ were accurate enough to be functional on other models that I've previously made, but is not guaranteed to be a production standard.
Description: Powder-coated one-piece barrel that appears on most Ions from the factory (some others came with SP Progressive barrels). This is a good demo for other SP barrels made from their 2006 series styles with flared muzzles.
Description: A one-piece Autococker-threaded barrel made by Custom Products. This particular was made for the FEP Quest marker.
Description: Dimensions used by KEE and Empire markers for their Autococker barrel threads. At the time of this writing, such markers would include Mini, Axe, Empire Sniper, BT markers, Resurrection Autococker, and Vanquish.
Description: Sample dimensions used for the male and female threads on All American fronts and Freak fronts made by Smart Parts. Note that these dimensions can also be used with the Empire Superfreak barrel fronts. The thread specification is 7/8-32-DL.
Also note that these barrel fronts have a small depression in their starting end which holds a Freak insert. To make All American backs compatible with this depression, AA backs have a small protrusion that takes up the unused space. This is only necessary if you were to make a barrel back that connects to a SP barrel front as shown.

Smart Parts Two-Piece Barrels:
These barrel backs and fronts are designed to mate with one-another to create a full barrel.
Description: Aluminum freak back (series 2002) with Autococker threading. Jewel not included.
Description: Aluminum freak back (series 2002) with Impulse/Ion/Nerve/NXT/Luxe threading. Jewel not included.
Description: Aluminum freak back (series 2002) with Shocker threading. Jewel not included.
Description: All American style barrel front for an SP back. This is a short 12 inch version (which only makes a 12 inch barrel when mated with an AA back).
Description: Freak style barrel front for an SP back. This is a short 12 inch version (which only makes a 12 inch barrel when mated with a Freak back)
Description: Model for a typical aluminum freak insert, this one happens to be the 0.689 [blue] model. For the record, the outside diameter of other Freak inserts isn't as critical of a dimension compared to the inside diameter (the bore size) and thus it isn't as tightly controlled. Sometimes, one-piece non-SP barrels that have been retrofitted to hold Freak inserts will not work very well with EVERY insert out there.
Dye Two-Piece Barrels:
Description: Ultralite barrel back, threaded for Autococker-thread markers.
Description: This barrel front mates with an Ultralite back to form a 16 inch barrel in total.
