I have a Barrel that I would Like to ID It is about 60" long, 2.00" OD at the Breach Face. 1.042"wide at Chamber, 9 Grooves Right Hand Twist (looking down the Bore). A 12 Gauge Bore Brush fits the Bore well. I will post some Photos so You can get an idea . Breach has Threads ( Broken Pattern ) for Quick Changing I assume and a Triangular milling moving toward the Muzzle .Take a Look Please. Any Help or Clue of where to go look would be helpful, Thanks

I'm no expert, just wild guessing, but you might search for specs on the Oerlikon 20mm cannons and similar guns used in WWII, and maybe more contemporary 20mm weapons. 20mm is about .79 inches. a 12 gauge bore is about .73, close enough that the 12 ga. brush would be almost right.

Looks like a Vulcan 20mm barrel

Thanks Guys I think You are correct !, now how did it end up where it did?

Not sure why, but they are more common than you'd think. Since it would be classified as DD without an exemption most guys make breech loading bp cannons from them.

Luckily this is considered a HBAR in MD so it will work on your next AR build.
