are you saying that 12ga and 20 ga stocks don't interchange between Wingmasters or between Wingmasters and Express...I have two stock sets from Wingmasters...12 and 20 and they appear to be identicle. Ken
Wingmaster versus Express has nothing to do with it, it's actually an age issue, so depending on the age of the stocks you have, they may or may not be identical. If I may explain, PRIOR to 1977, remington built their 20 gauge 1100's & 870's based on a 12 gauge receivers, so the stocks would interchange. Commencing in 1977, Remington modified the receiver for the 20's for less weight, also a smaller diameter magazine to go with it, hence the TRUE lightweights were born. So, prior to 1977 the stocks would interchage between a 12 & 20, 1977 and later they do not as the 20 gauge receiver became smaller, and hence, as Tractordan states the 20 will interchage with a 7600, 760, 7400, 742.
