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.

If you've ever done much work on your AR-15, you know that you will eventually need spare parts. When changing out handguards, it's relatively easy to bugger up the teeth on a standard barrel nut. That's where comes in. Have a replacement barrel nut ready so that you don't have to deal with the frustration of an incomplete project gun.
