The Aero Precision AR15 BAR Barrel Nut provides the critical interface between BAR-style handguards and standard threaded AR-15 upper receivers. Machined from billet 7075-T6 aluminum and finished in anodized black, this barrel nut delivers the precise fit that Aero Precision handguard systems require. We carry this component for builders who need a replacement nut or are assembling a new upper with Aero's proprietary BAR mounting system. The included shims allow proper timing of the gas tube with the upper receiver, a step that's essential for reliable cycling.
Aero Precision designed this barrel nut specifically for mil-spec threaded upper receivers, supporting AR-15 barrels with outer diameters up to .998 inches. The 7075-T6 aluminum construction keeps weight minimal while providing the structural integrity needed for a secure handguard lockup. Installation requires a standard AR-15 armorer's wrench and adjustable torque wrench—note that this barrel nut is not compatible with the Magpul Armorer's Wrench. Aero recommends torque settings between 30-45 ft-lbs; exceeding 45 ft-lbs risks damaging the barrel nut. The proprietary BAR interface ensures your handguard indexes correctly and remains stable under recoil, which matters for maintaining zero on mounted optics and accessories.
This barrel nut is the right choice for anyone building or repairing an AR-15 with Aero Precision's BAR-pattern handguards. Whether you're assembling a new rifle from components or replacing a damaged nut on an existing build, the included shim pack simplifies proper gas tube alignment. Made in the USA, it reflects Aero Precision's commitment to quality manufacturing. Browse our parts and accessories for additional components to complete your AR-15 project.
