AR-15 Multi Wrench (Single Ended)

  • 2967

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
  • 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)

This wrench is slightly nicer than other multi wrenches as the handle area is less busy and thus more comfy when in hand.  

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.

Note the current batch of wrenches has some slightly oversized torque wrench holes: The 1/2" square hole is actually 0.55". This means your torque wrench will still be able to apply torque but the ball detent on your torque wrench will not hold the AR-15 wrench attached. So you can still use it but you will have to take care to hole the two wrenches together. We have discounted the price to reflect this partial defect.


  • Notch sizes: 0.68" and 0.74"
  • Torque wrench hole: 0.55" for a 1/2" torque wrench stud
  • Steel construction
  • Weight: 485g
