A hand guard attachment assembly for a firearm having a barrel (30) and a receiver (20) fastened to the barrel (30) by a barrel nut (32). The hand guard attachment assembly includes a forearm (10) having a monolithic mounting rail/hand guard (16) that is removably connected to the receiver (20). The monolithic rail/hand guard (16) interfaces with an integral multi-slot mounting portion (24) of the receiver (20). A cinch block (12) is mated to the slots of the receiver (20) and held in place by the monolithic rail/hand guard (16). A tension block (14) is mated at one end of the monolithic rail/hand guard (16) and is attached to the cinch block (12) by a fastener (18) to securely hold the monolithic rail/hand guard (16) in place.
