The rear takedown pin is a critical component that holds your AR-15 lower and upper receivers together. This milspec replacement pin from IBOR-USA delivers the durability and precision fit you need for reliable assembly and disassembly. The black finish matches standard AR-15 components, and the design ensures smooth operation without binding or excessive play.
The rear takedown pin is one of the most frequently cycled components on your AR-15. This pin endures constant stress during assembly, disassembly, and field stripping. A worn or damaged pin creates play between the upper and lower receivers, which degrades accuracy and handling. This replacement pin restores that tight fit and ensures smooth operation every time you break down your rifle.
Milspec dimensioning means this pin fits standard AR-15 lower receivers without modification. The design accounts for tolerance stacking across different manufacturers, so you get reliable function whether your lower is from a major brand or a smaller builder. The black finish integrates seamlessly with existing components.
Over time, takedown pins wear from repeated use. Loose pins create movement between receivers, which affects everything from sight alignment to handling. Replacing a worn pin is one of the simplest maintenance tasks you can perform, and the improvement in receiver fit is immediately noticeable.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
