An anti-rotation handguard system, including a barrel nut having a barrel nut aperture formed therethrough, along a longitudinal axis of the barrel nut, wherein the barrel nut includes a registration groove defined around the outer periphery of the barrel nut; and an anti-rotation ring having a barrel nut aperture formed therethrough, wherein the anti-rotation ring further comprises a first anti-rotation tab extending from the anti-rotation ring, wherein the first anti-rotation tab is formed so as to be received within a gas tube channel of a handguard, and wherein the anti-rotation ring further comprises a second anti-rotation tab extending from the anti-rotation ring, wherein the second anti-rotation tab is formed so as to be received within at least a portion of a compression/registration slot of the handguard.

1. An anti-rotation handguard system, comprising: (a) a barrel nut having a barrel nut aperture formed therethrough, along a longitudinal axis of said barrel nut, wherein said barrel nut includes a registration groove defined by a recess around at least a portion of said outer periphery of said barrel nut;(b) a handguard having a handguard aperture formed at least partially therethrough, wherein a diameter of said handguard aperture is substantially similar to an outer diameter of said barrel nut, such that said barrel nut can be at least partially slidably inserted within at least a portion of said handguard aperture, wherein a compression/registration slot is formed within a portion of said handguard, so as to allow said handguard to be at least slightly compressed, and wherein one or more compression adjustment apertures are formed through said handguard, spanning at least a portion of said compression/registration slot, such that one or more attachment screws can interact with said compression adjustment apertures to reduce said compression/registration slot and thereby reduce said diameter of said handguard aperture;(c) a registration tab, wherein said registration tab is sized so as to be at least partially received within at least a portion of said compression/registration slot, wherein said registration tab includes an alignment aperture formed therethrough, wherein said alignment aperture is sized so as to allow at least one of said attachment screws to pass therethrough, and wherein at least a portion of said registration tab is sized so as to be at least partially received within at least a portion of said registration groove of said barrel nut; and(d) an anti-rotation block formed so as to be positioned and fitted within at least a portion of a gas tube channel of said handguard, wherein said anti-rotation block further comprises a gas tube aperture formed therethrough, and wherein said anti-rotation block further comprises an alignment tab portion that extends from said anti-rotation block and is formed so as to be at least partially positioned within said registration groove of said barrel nut. 2. The anti-rotation handguard system of claim 1, wherein said registration groove is defined by a recess formed around said outer periphery of said barrel nut. 3. The anti-rotation handguard system of claim 1, wherein said handguard comprises an elongate, tubular member extending from a first end to a second end. 4. The anti-rotation handguard system of claim 1, wherein said compression/registration slot is formed along a longitudinal axis of said handguard. 5. The anti-rotation handguard system of claim 1, wherein said gas tube aperture is formed along a longitudinal axis of said anti-rotation block. 6. The anti-rotation handguard system of claim 1, wherein at least a portion of said barrel nut aperture is internally threaded.
