AR-15 Armourer's Wrench w/Hammer

In stock

This specialized tool is designed to perform important screwing jobs when working on your AR-15. (full list at the bottom of this page) Plus the heavy end has a flat area to use as a hammer, convincer, or thumb detector.

(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.
