Embodiments of the invention can include systems and methods for installing a hand guard on a firearm. In embodiments, a method of installing a hand guard on a firearm can be provided. The firearm includes a barrel, a barrel nut, and a delta ring. The delta ring is retracted away from the barrel nut. A number of hand guard members are positioned about the barrel. An annular groove associated with each hand guard member is mated with a portion of a flange of the barrel nut. The flange is secured within the annular groove of at least one hand guard member. The delta ring is advanced over a portion of some or all the hand guard members.
