Re: Jewell issue, long after install.
If your going to pull it apart, look for microscopic particles of anything in/on or about the mechanism.
Don't pull it apart. Send it back the Jewell with a copy of the original receipt and a note explaining the problem.
What you describe is why I don't use Jewell triggers. My experience with them firing without the assistance of the shooter has made me wary.
I have a great woman, fantastic kids, a warm place to sleep and an accurate rifle. Life is good ..............
