The AR-15 Barrel Nut is a component that is necessary for the proper functioning of any AR-15 style firearm. For those who are looking to fully assembly their own AR-15 without using a pre-assembled upper receiver, this component is one that will be required. The barrel nut acts as an interface between the barrel and upper receiver, so any work done to change the barrel may also require a factory new barrel nut.
