And the rifles have been stone-cold reliable after averaging 300 rounds weekly for the past year. So for me, the use of anti-walk pins is not a negative, unless they were installed haphazardly.
If your Colt and FN pins are walking something is wrong or installed wrong. The anti rotate pins didn't fix it. They covered it up.
