Barrel Threads

[vDubLeics]

i was wondering if there was a guide to markers barrel threads, we know diffrent markers have diffrent threads but is there a guide to say what size of thread fits what guns...

the reason i ask is that i am working on my old Armson Assassin/rifle and i want to look for a new barrel for it but dont know what will fit.

I don't know anything about the marker but a quick Google brought up this

Versions: The original marker brought to the market was called the Armson Riffle. These were pump markers with an integral 13" Armson barrel. These were allegedly bought sometimes by people who just wanted the barrel (before Armson barrels were available for other markers). Later versions were called the Armson Assassin. Same body, but featured a unique-threaded, removable 16" Armson barrel.

So sounds like depending on your version you might have an interchangable barrel which I would assume is Autococker threaded, or some form of proprietary thread. Hope this helps. If not I'm sure someone more knowledgeable in the subject will be able to help
