The Aero Precision M5E1 Handguard Barrel Nut is used to connect Aero Precision M5 Enhanced Handguards to standard AR10 & DMPS pattern threaded upper receivers. This product comes with 5 shims to properly time the gas tube with the upper receiver.


  • M5E1 Handguard Barrel Nut (choose thread style from drop down menu - either ARMALITE threaded or AERO/DPMS threaded)
  • Shim Pack (5 shims)


  • Material: Machined from 1144 Stressproof® Steel
  • Coating: QPQ/Melonite
  • Torque to 65 ft lbs with a standard AR15 armorer's wrench (not included)

Please Note: If you intend to connect an Aero Precision M5 "enhanced" Handguard to a standard threaded upper receiver, you will need a M5E1 Handguard Barrel Nut. You will need to select between an Aero/DPMS threaded barrel nut or an Armalite threaded barrel nut, depending on your upper receiver.

If you have the 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.
