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.
