AR-15 Armourer's Multi-Wrench (Hook End)

99% of 100
In stock

This specialized tool is designed to perform important screwing jobs when working on your AR-15. It can torque the following parts:

  • Buttstock tube
  • Buttstock castle nut
  • Buttstock screws
  • Barrel nut (both types: standard and free-float handguard style)
  • Muzzle devices such as flash hiders and muzzle brakes

(If you don't need to work with barrel nuts, you might get away with using our Basic AR-15 Wrench)

There is a square hole for a 1/2" torque wrench (not included) to get the perfect amount of torque on your barrel nut (though many people use a calibrated wrist).

We also sell barrel nut grease to prevent thread seizing.


  • Notch sizes: 0.68" and 0.74"
  • Torque wrench hole: 1/2"
  • Slotted screwdriver on the end
  • Steel construction
  • Weight: 550g
  • Dimensions: 325 x 50 x 25 mm (L x W x H)

You get:
