Precision Reflex AR-10 Barrel Nut Wrench

The Precision Reflex AR-10 Barrel Nut Wrench (brand part no. 030085) is a gunsmithing tool built by Precision Reflex specifically to fit the barrel nut on an Armalite-pattern AR-10 upper. Attempting to break a barrel nut loose with a strap wrench or adjustable pliers risks slipping and marring the finish or rounding the nut’s notches; this wrench engages the nut’s flats directly so a bench vise or torque wrench can apply real force without damage. It’s a purpose-built solution for barrel swaps, headspacing work, and general AR-10 upper maintenance.

Key Specifications

• Purpose-built to fit the barrel nut on Armalite-pattern AR-10 uppers, not a generic strap wrench.
• Engages the nut’s flats directly for slip-free leverage during barrel swaps or headspacing.
• Sized for single-nut use at the bench, pairing with a vise or torque wrench.
