Warne Mounts has developed this mounting platform specifically for the AR-15 class of rifle. It is manufactured as a single unit, including the base and rings. Made of Aircraft Aluminum for weight, it secures to the flat top of the rifle with a steel mounting mechanism for strength. Secured by two 1/2" nuts to the rifle, these Unitary rings are capable of handling as much rough use as your AR can give them.
