What Is An Armorers Wrench?

There are many armorers wrenches available, but they can vary in the features and capabilities they provide. The most basic function an armorer’s wrench provides is to tighten the castle nut when installing the buffer tube of an AR-15 rifle.

Many armorer’s wrenches also provide features to tighten barrel nuts, flash hiders, and other muzzle devices.

What separates these armorer wrenches from each other is the number of features they have and the build quality. In the case of armorer wrenches, you get what you pay for.

Some of the cheaper choices will work fine if you’re only going to use it once or twice. If you’re doing gunsmithing tasks more regularly, then you’ll want to spend a little more for the higher build quality and available features.
