Are you attaching this handguard to a standard threaded upper receiver?

Make sure to select “Yes” under the BAR Barrel Nut option above (shims included). Our handguards use the BAR interface and do not work with a standard barrel nut. If you are using our M5E1 Enhanced Upper Receiver, no additional pieces are needed.

*Please note – This handguard is specific to the M5E1 platform. It is not compatible with the AR15/M4E1 platform. May not be compatible with all offset sights. *Polymer front Magpul MBUS sights may require modification to the sight for installation.
