Alright, we’re not deleting I guess.
Summarization of the previous OP.
Looking to start a tracker for gas port sizes that’ll hopefully help people when searching for a barrel to suit their needs. I’ll eventually make this publicly accessible and figure out a good way to make it searchable using a wide variety of parameters.
I’m only looking for first hand info. You’d need to ensure you’re using the correct tools to collect your measurement (pin gauges) and not something like calipers, which can’t accurately gauge a gas port. Manufacturer advertised port sizes would work too, but it would have to be documented (posted on their website, in an email, etc).
Info needed would look something like this:
Manufacturer:
Model (If applicable):
Cartridge:
Barrel length:
Gas system length:
Gas port size:
Manufacture year/date (either date code on barrel or approximate from your memory):
Other variables that you’d deem relevant (complete gun vs component, etc):
