Aero Precision AR15 BAR Barrel Nut

The AR15 Bar Barrel Nut connects BAR-style handguards to standard threaded upper receivers. This product has 4 shims to time the gas tube with the upper receiver properly. Compatible with mil-spec threaded upper receivers ONLY.


  • Material: Machined from Billet 7075-T6 Aluminum
  • Coating: Anodized Black
  • Torque with standard AR15 armorer’s wrench (Does not work with Magpul Armorer’s Wrench)
  • Supports Mil-Spec AR-15 barrels with outer diameters up to .998 View
  • BAR Barrel nut

Please Note: All Aero Precision Handguards use the BAR interface. If you intend to connect an Aero Precision Handguard to a standard threaded upper receiver, you will need a Bar Barrel Nut. If you have our M4E1 Enhanced Upper Receiver, you do not need a BAR Barrel Nut as the barrel nut and rail mounting platform is forged directly onto the upper receiver. *Recommended torque settings between 30 – 45 ft-lbs. Torque over 45 ft-lbs may result in damage to the barrel nut.


  • BAR Barrel Nut
  • BAR Shim Pack (8 shims)
