The AR-15 Barrel Nut is an all-steel military-spec component for the AR-15 platform. These AR-15 barrel nuts are precision machined and have a black oxide finish that will prevent rust or corrision. This component is an essential component for the functioning of your rifle with it being installed on the barrel assembly, fitting between the barrel and delta ring.

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.
