Identify This Barrel (Equation Multiple Switch?)

Picked up a bunch of old barrels, and sorting through them I came across this one. After a little research, it appears to be a Equation Multiple Switch dual bore barrel.

The back is 9" and .6925 bore, and the tip is about 3" and .693 bore.

Does anyone know anything about these? Any links I've found to Equation's site are dead.

And the big question is, what is it threaded for? I checked it on everything I own, and it doesn't seem to fit anything. That includes Spyder / Piranha, Autococker, Tippmann 98 and A5 / F4 Illustrator, Azodin, GoG, or even Brass Eagle.

Is there a back section that is missing?

Any help sure would be appreicated.

Everything I'm seeing says these were an insert-based system. Distribution wound up being through Tracer Paintball, which would have eventually (originally?) been part of NPS. I believe the EQ inserts would be on the right of this case:



Teflon coated inserts. Here's another image without the Freak inserts, this one being a "Pro" series barrel set:



Interesting that the retention o-rings are on the inserts. If you use the name "Bizerk" in your search, that seems to help.

Not sure on the threading on the back, though. Indian Creek threads was the closest thing, and that still might not be right.
