Anyone know what is the diameter of the gas port on the 20" Cardinal Armory / Ko-tonics barrels with rifle-length gas systems? This info would be greatly appreciated.

See if HTR or Owenslee can help you out.

A 20" barrel with rifle gas system has a gas port of: .1067" diameter...or a #36 drill.

owenslee, you are my new best friend. I figured it needed to be bigger, but whoa, that's big. I have that drill bit on its way to me via Mcmaster-Carr. Thanks!

Best informed mods on the shooting net. Between these two theres not a lot of unknown.

It would be interesting to see what the Stag 7 is too for reference.

I haven't had one to measure...so I can't help you on that one.
