There will be plenty enough people in the coming years who won't be able to write, only type (sort of) :(

No worries.
I would think the marlin one would only be different enough to get round the patent.

If its a savage accutrigger and the trigger is getting stiff, then yes it needs a clean and just the smallest drop of lubricate and it should go back to normal. Not hard to do, did mine last year.

Always best to check afterwards. I have a torque screwdriver if you need one.
