Got your hands on an Aero Precision handguard you're looking to put onto your AR-15? Grab Aero Precision's AR-15 BAR Barrel Nut, designed specifically to interface with all of Aero Precison's Enhanced handguards when used for installation on a mil-spec, threaded upper receiver.

This Aero Precision AR-15 BAR Barrel Nut is purpose-built for use with the company's M4E1 Enhanced Upper Receiver, but the nut will work with pretty much any mil-spec AR upper receiver on the market. Each barrel nut is machined from 7075-T6 aluminum and includes 4 shims to aid in installation.

Total weight on the barrel nut is 2.24 ounces.

INCLUDES:

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

FEATURES:

• 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”

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 Aero Precison's M4E1 Enhanced Upper Receiver, you do not need a BAR Barrel Nut as the barrel nut and rail mounting platform are forged directly on to the upper receiver itself.

*Recommended torque settings between 30 - 45 ft lbs. Torque over 45 ft lbs may result in damage to the barrel nut.
