Cover most of your AR-15 service needs with a single tool.  An innovative layered and laminated stamped steel construction makes the Delta Series Combo Tool the most durable AR tool available. This construction method allows the use of hardened steel barrel nut pins designed to hold up to heavy torque requirements. A cut out for a 1/2″ drive allows the tool to be used with a torque wrench or ratchet driver. Profiles for buffer tube lock nut and flash hider are included. The addition of a bit driver and bit holder with six common bits adds to the versatility.    Includes a torque wrench to ensure proper barrel nut torque for maximum accuracy.
