I recently purchased a used R51.  Serial # is 20,0xx.  Supposedly it was manufactured in 2016.  I "presume" it is 2nd generation, well after the recall.  Seems to function fine, including with my cast bullet reloads.

Does anyone know the "cut-off serial number" for 1st generation?  One report suggest it is 4,000?

When I phoned Remington this week, the customer service rep kept insisting "There is no recall on R51's."  Very strange considering previous publications direct from Remington.
