- AX556 owners please note that the EPP (Enhanced Pivot Pin) is incompatible with the AX556 receiver due to the receiver's proprietary design. The ETP (Enhanced Take-down Pin) will work as designed.
- Depending on your M16 receiver, may not be compatible with the KNS anti-walk sear pin without modification to the KNS anti-walk sear pin. 3. Neodymium magnet is not a toy. Use only for the installation of the EPP. Keep out of reach of children.
