What is an armorer’s wrench used for?

Basic Armorer's Wrenches are used to tighten the castle nut while installing a buffer tube in your AR 15. However, Armorer's Wrenches come in many forms and can offer different functions depending on the type you choose. There are armorer’s tools and tool kits for tightening flash suppressors and other muzzle devices or loosening or tightening pin-style barrel nuts. Armorer's Wrenches can also be used in the installation or removal of rifle receiver extensions.
