The Aero Precision M4E1 AR-15 5.56 Rifle Barrel Complete Upper Receiver has the handguard mounting system forged into the upper receiver. So the Aero Precision M4E1 AR-15 5.56 Rifle Barrel Complete Upper Receiver is only compatible with the Aero Precision M4 Enhanced Handguards. If you are using the M4 Enhanced Handguards with a standard AR15 upper receiver that is not an Aero Precision M4E1 upper you will need the Aero Precision BAR Barrel Nut.
