Just wanted to post this here since I haven't seen it posted yet. Patternmaster sent out a recall on some of their code black chokes. Sure enough the choke I bought last year was included in this. After contacting patternmaster they sent me a shipping label and was able to get it sent back to them for a new choke. Overall I was very pleased with their customer service and was even able to get the bad choke swapped out for a different style to fit my new gun. Here's the recall to see if it might include you.
