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

Includes:

  • M5E1 Handguard Barrel Nut
  • Shim Pack (5 shims)

Features:

  • Material: Machined from 1144 Stressproof® Steel
  • Coating: QPQ/Melonite
  • Torque to 65 ft lbs with a standard AR15 armorer's wrench
  • Weights: 5.4oz

Please Note: If you intend to connect an Aero Precision 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 and an Armalite threaded barrel nut, depending on your upper receiver.

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.
