Cmc triggers anti walk pins - CMC Triggers Anti Walk Trigger Pin Kit For Smith & Wesson M&P 15-22 Only 91403

Definitely oversight on my part but these pins are for a specific model m&p 15-22. This is listed in the description, but as a novice I saw anti walk pins and didn’t realize there were multiple lengths and diameters. I have reordered the correct small pin kit from this same manufacture. No issues with the manufacture, packaging or items received. They operate as intended. Just simply too long for my lower.
