This is to all the guys who have built 870 20 gauges into dedicated turkey guns. I want to put a 12 gauge stock on my 20 gauge and will be using the Lucy adapter. I also want to use the matching forearm but will the 12 gauge forearm fit on the slide of my 20. It is an Express and currently has a wood forearm. I was planning to use the EX Performance stock and forearm. Thanks.
