clef multifonction master

The MASTER multifunction key is perfect for assembling/disassembling and customising an AR15.
With its ergonomic design for a good grip, anyone can precisely adjust the torque for barrel nuts, muzzle brakes, bolt extensions or stocks without damaging them.
In addition, it features a steel hammer at one end with three interchangeable tips made of different materials (nylon, bronze and rubber) stored in the handle of the wrench.
