The action isn't nearly as smooth as I would expect, particularly as the bolt closes. I can see a fair amount of debris around the lugs but I can't get to it with removing stuff.
Where's the O-ring that was mentioned? Does it seat the magazine tube to the receiver?
Thanks everyone for your input.
No, the O-ring is what keeps the action quiet.. When it's gone, the fore-end assembly will 'rattle'. If it's just out of position, the action will be stiff to operate. Only way to get at it is to remove that action tube..
