Best anti-walk pins you can buy! - Yankee Hill Machine Anti-Rotation Pin Kit (Gen2 Mod2) By KNS

This is an absolutely superb product. Build quality is unrivaled, and the torx screws this system utilizes are much more sturdy and significantly less prone to stripping/deforming than the more common micro hex screws and allen keys that come with other kits. This system completely eliminated all rotation and wobble from my trigger pins. When milling my lower, the old drill bit malfunctioned, walked, and ended up milling way too large of a hole, so large that standard .154 pins would simply fall out. This system, combined with a Timney drop-in trigger completely fixed all problems. Although the cost of this system is a bit much compared to similar products, it is definitely in a league of its own and worth every penny if you are looking for the absolute best of the best anti-walk pins currently on the market.
