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 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.
AR15 BAR Barrel nut is available at Premium Outfitters USA! We are an Aero Precision preferred stocking dealer. Order your Aero products with confidence.
