Aero Precision M5E1 Handguard Barrel Nut

DPMS Thread

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


  • Handguard Barrel Nut
  • 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

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

If you have our M5E1 Enhanced Upper Receiver, you do not need this M5E1 Barrel Nut as the barrel nut and rail mounting platform are forged directly on to the upper receiver itself.
