So my Affinity 3 (was bought in December of last year) is failing to eject a spent shell, causing it to get stuck in the ejection port and cause a double feed. I keep my guns cleaned and oiled, was shooting a Stoeger 2000 before and never had an issue. Same lube and cleaning regimen. The Affinity has jammed with Winchester Super X 3in steel #3s, Super X 2.75 lead #4s, Kent Fasteel 2.0 3in #2s, Boss 2.75in #5s, Federal Target loads, and Winchester Target loads. I talked to customer service and they’re shipping a shell stop/release out, but I was looking for guidance on how to replace that part and why it’s causing an issue? Thank you for any input.
