What Gas tube lenght??

[45C]

Hey I’ve been looking for a GT but not exactly sure what I need, my barrel is measuring 8 3/16 from the breach/ barrel extension to the center of the gas port hole.

So it’s kinda in the middle of carbine and Mid ?

That's carbine. Extension to shoulder should be about 7.8"
