M5E1 Handguard Barrel Nut - AERO/DPMS Threaded

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

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 our 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.
