I was looking for the o-ring sizes for my QB Chief and not having any luck. While I was looking I found a chart. Basically what you need to identify an o-ring is it's inside and outside diameter and it's thickness. What is new is the way I found these. I didn't have a ruler handy so I simply called up an online ruler on my phone and laid the o-ring right on top of the ruler. You can drag the on screen ruler up and down to match where the o-ring lays on the screen. I found in this case that the barrel O-rings are metric 10x2. In other words the outside diameter is 14mm, the inside is 10mm and the thickness is 2mm. It is really easy to see the ruler lines under the o-ring. You can use either metric or English measures.
Anyway, I hope this helps someone out besides me!

Is the screen ruler in the App Store

Can you please post a link

Great info, but how about letting us know the name of the app you are using, since there are probably hundreds of measuring apps available. A screenshot of the app would be a bonus.

The one I use is iMetalbox. Part of a 12 pack of handy gadgets.

I inadvertently tried posting a link on another post. It was inside a quote of all places,. The system kicked me out and I lost all of my text.
I use android devices and have found several in the play store.
This method I think gets you close, but I agree that a caliper is better.

I agree with you, but not everyone has calipers. I think the on screen measurement is only approximate.
