That was brand new issue...

Works every time! I skipped that part of the video and went right to the shooting.

If polishing doesn't work, you could install a sub caliber insert and have an easy shooting rifle.

Do you know of a company or shop that does that? I'm pretty sure my local gunsmith won't do that. Since the numbers on the barrel and receiver match, this would be great option to keep them together.
