Review on 🔒 Ultimate Stability with WSERE Anti Walk Rotation Precision Non Rotating: Say Goodbye to Unwanted Movement! by Keith Alvord

They are very cheap. I removed the first one I wanted to install. I got them to fix the 'real' pin walking problem. If you have the money and time to wait, get KNS Precision. I have KNS on another set of triggers and they are very high quality. These anti-walk pins aren't a serious long-term solution.
