Twistlock barrel ID needed

[Calvin]

I got an offer for a classic mag on ebay. Considering it, but am wondering what barrel this is. Anyone have a clue?

I see "Pro Power" lasered on it. Taso? The porting and additional milling is unusual for Taso though.

Its definitely not a Taso Pro Series.

Looks like a j&j brass or stainless that had the option of custom lasering thumb to it.

They used to offer that for fields to logo there barrels

The two types of porting, straight and spiral, on the same barrel evoke j&j or boa in my head. Not sure if Boa ever did lasting, but it wouldn’t surprise me since they came from j&j.

Does it have straight rifling in the barrel?
