I am wondering if I can fit a Mossberg 500 12 GA. forend to a 16 GA Mossberg 500? My concern is the diameter of the magazine tube. Or should I look into a 20 GA forend?
I assume you own a 16 ga 500B and need a new forend. Why don't you measure the diameter of the forend tube you have and post it so someone can tell you if it's the same as a 12/20 ga?
