I'm new on here and this is my first post.
I recently received a new T8 from Jackson's which was a replacement for one that was showing rust problems after 4 years use.
I had a zero session yesterday and the rifle grouped well.
The problem is that when I removed the moderator to clean it, I noticed that there's a metallic rattle coming from it now!
I have tried, with no success, to shake the foreign body out.
I'm using the plastic bush from my original T8 and I checked that the moderator was "centred" by looking through the bore before use.
Any advice would be appreciated.
