The aluminum takedown pins are enhanced AR-15 components from Battle Arms Development. Battle Arms machines these pins from lightweight aluminum for a custom look. Each set includes both the takedown pin and pivot pin for mil-spec AR-15 builds. In addition, these pins come in multiple anodized colors including red, blue, and purple. They drop directly into standard lower receivers with no fitting required. Therefore, builders can add a distinctive color accent to any AR-15 build. Daytona Tactical stocks these enhanced pin sets in multiple colors at competitive prices.
