Geissele Automatics Barrel Nut Wrench AR-15/M4 Steel

The Geissele Automatics Barrel Nut Wrench is a precision armorer's tool engineered for installing and removing barrel nuts on the AR-15/M4 platform. Machined from steel, this wrench is purpose-built to drive both Geissele barrel nuts and standard Mil-Spec AR-15/M4 barrel nuts.

A square drive in the body accepts a standard 1/2-inch torque wrench handle, letting you apply accurate, repeatable torque during barrel nut installation - a critical step when mounting Geissele Super Modular Rail handguards and other free-float systems, where proper torque directly affects rail alignment and long-term reliability. Its compact, low-profile design slips easily into an armorer's bench drawer or a field bag, making it a must-have for anyone assembling or servicing an AR-platform rifle.

Compatibility:

• All Geissele rails and handguards
• Mil-Spec AR-15/M4 barrel nuts
