Claim Text:
1. A handguard attachment system, comprising: (a) a handguard comprising an elongate, tubular member extending from a first end to a second end, wherein at least one handguard attachment aperture is formed through said handguard proximate said first end of said handguard; (b) a barrel nut having a barrel nut aperture formed therethrough, wherein said barrel nut includes a registration groove defined by a recess around an outer periphery of said barrel nut; (c) a compression collar having a compression collar aperture formed therethrough, wherein a diameter of said compression collar 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 compression collar aperture, wherein an outer diameter of said compression collar is substantially similar to an inner diameter of at least a portion of said first end of said handguard, such that at least a portion of said compression collar can be slidably inserted within at least a portion of said first end of said handguard, wherein a registration/compression slot is formed through said compression collar, so as to allow said compression collar to be at least slightly compressed, and wherein one or more compression adjustment apertures are formed through said compression collar, spanning at least a portion of said compression/registration slot, such that attachment screws can interact with said compression adjustment apertures to reduce said registration/compression slot and thereby reduce said inside diameter of said collar aperture, wherein at least one collar attachment aperture is formed at least partially through said compression collar, and wherein placement of said at least one collar attachment aperture corresponds to said placement of said at least one handguard attachment aperture, such that when said compression collar is aligned with and at least partially inserted within said handguard, said at least one collar attachment aperture is aligned with said at least one handguard attachment aperture so that an attachment screw may be positioned at least partially through said at least one handguard attachment aperture and at least partially into said at least one collar attachment aperture to secure said handguard to said compression collar; and (d) a registration tab, wherein said registration tab is sized so as to be at least partially received within at least a portion of said registration/compression slot, wherein said registration tab includes an alignment aperture formed therethrough, wherein said alignment aperture is sized so as to allow at least one attachment screw 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.
