Abstract
A firearm includes a receiver and a barrel connected to the receiver. A hand guard extends from the receiver and defines a hand guard bore. The receiver includes a threaded end and the hand guard includes a flange extending into the hand guard bore and abutting the receiver about the threaded end. A hand guard nut abuts the flange of the hand guard and threadedly engaging the threaded end of the receiver. The hand guard nut sandwiches the flange between the hand guard nut and the receiver for attaching the hand guard to the receiver. The hand guard includes a first hand guard portion and a second hand guard portion removably attached to the first hand guard portion. The second hand guard portion is slid from an assembled position to a disassembled position to expose the hand guard nut in the hand guard bore.
