Waterfowlhunter, we got the R3 on Friday and put it on. Man, the screws in the Wingmaster were hard to get out! Of course, I guess that happens when they have been in there since the gun was bought 35 years ago. Anyway, thank the Good Lord we got them out, got the new pad on and it fits pretty well. Not perfectly, if you are a real perfectionist it may not be good enough, but it was for us. I thought it was just a little off center, but overall, I was pretty pleased. Dad shot the gun Sat and I asked how it did and he said he didn't even notice it. In the past, he did. He only shot 2-3 times, so we will see how he likes it after he hopefully (Good Lord willing) shoots it more. But right now, it seems like a pretty good fit and a good buy.
