Need a Barrel ID

[Lopez17]

We bought a gearbag of stuff yesterday from a local player. There's a barrel in there (shocker threaded) that we can't ID. It's got some sort of spiral threaded honing/rifling on the inside. Anyone more knowledgable than me know what this is?

That barrel looks kinda old.... I looked at most of the barrels here on PB review. But no luck. Sorry.

I think it's an Armson but we're not 100% sure. It's clearly shocker threaded though.

You're right. Definitely an original Armson.
