My Stevens 5100 20 ga has "Ranger 101.6" stamped on the side. If it's a 5100 it's usually stamped on the right side. I believe the pin arrangement is different on the 5100 and 311. The 5100 has the lower pin closer to the stock.

I do not know if the stocks for 12 and 20 ga are interchangable.

Good luck.
