Ok, so the silencer does it's job beautifully - but....
I now have some accuracy problems! Initially it was fine, grouping just as well as before, but I did have a couple clip the end of the silencer so I had a go at re-shimming it.
The silencer is now in line with the barrel, but accuracy have gone to pot...any ideas why this may be? They're definitly not clipping any more, and co2 is good (ie, not dead).....
