To save yourself from boogering up the factory one time use aluminum nut, these tool steel nuts are a direct replacement and are able to be reused countless times.
They will work with older factory KAC URX wrenches, or the aftermarket ones we made in the past.
Barrel nuts come with a black oxide finish which gives a dull matte black appearance.
Note: some customers have noted figment problems with the newer style of factory Knights Armament wrenches that are noted by having drill corners in the drive square.
