Please Note: If you have an Aero Precision M5E1 Enhanced Upper Receiver, you do not need a M5E1 Handguard Barrel Nut as the barrel nut and rail mounting platform are forged directly on to the upper receiver itself.
POLICY: We cannot accept returns or offer refunds for barrel nuts. It is your duty to make sure that the barrel nut you are ordering from us is correct for your upper receiver, handguard, and/or intended use.
