A rugged and reliable tool to meet most of your AR-15 servicing needs. It’s constructed of innovative layers and laminated stamped steel, making it one of the strongest AR-maintenance tools you can buy. This construction method allows the use of hardened-steel barrel-nut pins capable of standing up to heavy amounts of torque. The 1/2" cutout accommodates a torque wrench or ratchet driver. Profiles for a buffer-tube lock nut and flash hider are included. The tool also includes a bit driver, bit holder and six bits commonly used to service AR rifles.
