Hi! I recently joined the forum as this appears to be where the best content is!
I searched the forum and didn't find anything (or my search skills are lacking).
I picked up a 22LR barrel blank from Green Mountain and I'm working with a local machinist to chamber and profile it for a dedicated AR22LR build with a CMMG dedicated bolt (not a conversion kit with a chamber adapter).
The part I haven't been able to find, what are the dimensions of the chamber end of the barrel (from the barrel extension shoulder and back)? Hopefully that makes sense, if not, here's a picture of what I'm struggling to find, dimensions inside the blue box. Specifically, the dimensions of the "nipple" that interfaces with the dedicated bolt collar.
Does anyone have a drawing I can reference or a link to point me in the right direction?
Thanks!
