I found this site searching for information regarding parts for a 1975 standard weight 20 gauge (serial # ends in X). I bought this gun for my 11 yr old this past summer as his first gun. Great gun, good fit for it has a short length of pull. I did not realize these models had 12 guage adapted receivers until the feed latch tip broke off and I tried to get a part. Remington sent me a light 20 part which did not work. I called them back today. They stated no parts made for this gun but would send a 12 gauge feed latch at no cost to let me try. Anybody ran in to this before? Any help would be appreciated.
