I think this is the thread you're looking for.
Looks like I'm about to do this myself. Finally got out to function test the 16"GB that I put in a build for a friend of mine. Chambered a round and then tried to eject it. I had to use a rubber mallet on the CH to get it to extract. Scratches all over the case. I used a sharpie on the bullet to see if it was being driven into the lands as in a short chamber. Again, had to beat the CH to eject the round. Bullet looked fine so I decided to go ahead and fire one round from the hip. No ejection but I found a gas block issue so I'm not too concerned about that. It still required considerable force to manually eject the case but was slightly easier.
I'm going away for the weekend but hope to be able to tear this down and closely check the chamber and extension next week.
