I have a Belgium Sweet Sixteen that I need to put a new stock on. I assume that it takes the same stock as the 20 Gauge. What is the difference between the 20 gauge stock and the 12 gauge stock, and are they interchangeable? It is a round knob. I found an original 12 gauge in great shape with the horn buttplate, but it is for a 12 gauge. Will it work?

NO
