Bored and waiting for 12:01, 2013 - came across this. I can only add that a few? 71s and 71/84s were converted into shotguns called the Remo-Popular. I suppose if one could find a barrel etc. they could be retro-fitted back to a rifle.

I have a 71 R-P, 12 gau. in a take down, interesting gun. --- John
