Anyone have a pic of barrel for M11

[sigfla]

I need a close up pic of the breech area of an M11. I am wondering if I need a small cut out in the breech for my extractor to engage the rim of my shell casings. My RPB upper didn't have this trouble but my stock one does. Shell fires but stays in the breech very tight and I have noticed that my extractor is slamming the edge of my barrel at the breech end. Seem to remember someone on another board referring to a small cut that should be there.

Extractor relief...

will be necessary to allow proper access to the rim/groove of the .380acp cartridge. A dremel will be required to remove a *minimal* semi-oval portion of the chamber w/o compromising support during ignition. GO SLOW & use snap-caps to test!

Sorry... as I have no photos to illustrate this.
