Manufacturer Gas Port Dimensions

Correct. I have a hard time believing it, even though the representative said he confirmed it by measuring twice.
So the rep literally measured one of their barrels right then?

If so, I wonder if he used calipers or a pin/dowel gauge. If calipers, I could see that not being entirely accurate simply because of how small a gas port it. What weight buffer do you run? Also, any suppressed shooting?

I run an H buffer unsuppressed.

And I just reviewed the email and he did say he used calipers.

Can this chart be hosted to Google Forms or something so it can be updated and kept synced?
Working off of Jackrabbit's data, and utilizing the information in this thread, I've started this: https://docs.google.com/spreadsheets/d/1tXunBDX5Gaz87BqxwNxDUlWNK9nEv-cZEQoLq2JXXrk/edit?usp=sharing

If y'all have any more information, please submit it here; it'll auto-populate onto the previous spreadsheet, though the formatting might be off, but I'll clean it up periodically: https://goo.gl/forms/gxSiVMP0jITBxV2v1

I called up Daniel Defense to ask their gas port sizes for 14.5" carbine length gas systems. The tech said they were .067" across the board. I thought DD was following mil-spec gas port sizing for 14.5 and 16 carbine length gas systems? Since when did they start opening up their gas ports for the dirt clod shooting crowd.
