I don't think it was just a reliability issue with the A-5. It is still the same way. I still know people that hunt with them but you do not see them on the clay field. For my part as a kid my father owned a Rem 11. He thought that it was the greatest thing in the world. I could not hit anything with it but someone had a Win Model 12 that worked really great for me. Could have been the stock dimensions or balance. I do not know.
I did see a 16ga ducks unlimited A-5 that was pretty nicely done last week.
