Precision Reflex DPMS/KAC .308 Barrel Nut Wrench

The Precision Reflex DPMS/KAC .308 Barrel Nut Wrench (brand part no. 03-0086) is built by Precision Reflex to fit the larger .308-pattern barrel nut found on DPMS and Knight’s Armament (KAC) AR-10-style uppers. The .308 pattern nut differs in diameter and notch spacing from a standard AR-15 barrel nut, so a wrench sized for the smaller platform won’t seat correctly or apply even torque. This wrench matches the DPMS/KAC pattern precisely, letting a builder or gunsmith break the nut loose or torque it to spec without risking a slipped tool and a marred receiver extension.

Key Specifications

• Sized specifically for the DPMS/KAC .308 barrel nut pattern, distinct from standard AR-15 nuts.
• Matches the nut’s notch spacing precisely to prevent slipping during torque work.
• Built for use with a bench vise or torque wrench during barrel installation or removal.
