DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(36) The claimed subject matter is now described with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced with or without any combination of these specific details, without departing from the spirit and scope of this invention and the claims.

(37) Referring to FIGS. 1-4 the preferred embodiment of the handguard assembly 10 is illustrated. The handguard assembly 10 can be any size and shape and made out of any number of components. In the preferred embodiment the handguard assembly 10 comprises an upper component 100, a lower component, 200, a front cap 300, a rear cap 400, and a plurality of screws 500.

(38) As shown in FIGS. 5-7, the handguard assembly 10 is mounted onto the front end of a firearm 20. The upper component 100 is positioned on top of the gas tube 22. The rear cap 400 attaches to the bottom receiver of the firearm 20. The front cap 300 attaches to the barrel 24 of the firearm 20. The bottom component 200 attaches to the front cap 300 and rear cap 400 by the plurality of screws 500. The upper component 100 attaches to the lower component 200 when fully attached to the firearm 20. The handguard assembly 10 positions the gas tube 22 and barrel 24 into the correct positions so that the front sight 30 and rear sight 32 are zeroed when the handguard assembly 10 is attached to the firearm 20.

(39) Referring to FIGS. 8-9C, the lower component 200 is illustrated. The lower component 200 may be any size and shape and include any number of portions or components. The lower component 200 is a generally cylindrical member. The lower component 200 has screw holes 220 for receiving the screws 500. The lower component 200 has an opening at the top for positioning the lower component 200 on the barrel 22. The top end of the lower component 200 is angled relative to the sides. The top end has one or more slots 210 positioned on each side of the top opening. On the bottom side of the lower component may be one or more apertures 230. The apertures 230 may be any size and shape. The apertures 230 permit a user to hang the firearm on a rack and permit the user to grasp the firearm by the lower component 200.

(40) Referring to FIGS. 10-11C, the preferred embodiment of the upper component 100 is illustrated. The upper component 100 may be any size and shape. The upper component 100 is generally U-shaped with an open bottom for receiving the gas tube 22 of the firearm. The upper component has a front opening 120 and a rear opening 130 through which the gas tube 22 passes. In the preferred embodiment the front opening 120 is vertically lower than the rear opening 130 so that the gas tube 22 passes through the upper component at a downward angle. In other embodiments the front opening 120 and rear opening 130 are positioned at the same height and the gas tube 22 is not forced into a downward angle. The upper component also has one or more tabs 110 on each side of the upper component 100. The tabs 110 of the upper component 100 fit into the slots 210 of the lower component 200. As illustrated, the upper component has a picatinny rail 140. In other embodiments the upper component 100 does not have a picatinny rail 140.

(41) Referring to FIGS. 12-13C, the rear cap 400 is illustrated. The rear cap 400 has a rear cap top side 410 that is U-shaped for receiving the barrel 24 of the firearm 20. The rear cap 400 has screw holes 420 for receiving the screws 500 to attach the lower component 200 to the rear cap 400. The rear cap 400 has a rear tab 430. The rear tab 430 may be any size and shape and is preferably utilized to attach the rear cap 400 to the lower receiver of the firearm 20.

(42) Referring to FIGS. 14-15C, the preferred embodiment the front cap 300 is illustrated. The front cap 300 has a front cap top side 310 that is U-shaped for receiving the barrel 24 of the firearm 20. The front cap top side 310 is higher than the rear cap top side 410 to force the barrel into an upward angle. In other embodiments the front cap top side 310 is at another position which does not force the barrel 24 into an upward angle. The front cap 300 has one or more screw holes 320 for receiving the screws 500 so the lower component 200 can be attached to the front cap 300. In some embodiments the front cap 300 has a circular hole 330 passing through the body of the front cap 300. The circular hole 300 permits the cleaning rod 40 to pass through front cap 300.

(43) As shown in FIGS. 16-17B, the upper component 100 fits together with the lower component 200. The front cap 300 is fully positioned within the lower component. As shown in FIG. 17B, the tabs 110 of the upper component 100 are secured within the slots 210 of the lower component 200.

(44) Referring to FIGS. 18-21, the invention is illustrated in another embodiment. In this embodiment the lower component 100 is longer and extends further along the barrel 24. The operation of the invention in this embodiment is the same regardless of the longer lower component 100.

(45) Referring to FIGS. 21 and 22, the position of the upper component 100 and lower component 200 on the firearm 20 are illustrated. The upper component 100 is locked into place by the gas tube lock 26. The gas tube lock 26 forces the upper component 100 to push down on the lower component 200. The angles of the structure of the upper component 100 and lower component 200 cause the upper component 100 to squeeze the lower component 200. This squeezing action forces the alignment of the upper component 100 and lower component 200. This, in turn, forces proper alignment of barrel 24 with the gas tube 22, zeroing the front sight 30 and rear sight 32. The structure of the handguard assembly 10 is such that a user may remove and reinstall the assembly without losing mounted sights zero. As shown in FIG. 22, the gas tube lock 26 fits within the locking hole 28. The gas tube lock 26 is utilized to lock the gas tube 22 into proper position in the upper receiver of the firearm 20.

(46) Referring to FIGS. 23-24B, the elongated lower component 200 is illustrated. The elongated lower component 200 comprises slots 210, screw holes 220, and apertures 230.

(47) When the tabs 110 of the upper component 100 are fit within the slots 210 of the lower component 200, the tabs 110 pull the sides of the lower component 200 inward, causing the lower component 200 to apply pressure to the front cap 300 and rear cap 400 and squeeze the barrel 24. The entire assembly thus becomes locked into optimal place where the sights are zeroed. In this embodiment the distance between the tabs 110 on the opposite sides of the upper component 100 is less than the distance of the slots 210 on the opposite sides of the lower component 200. In other embodiments this distance may be equal or greater than the distance of the slots 210 on the opposite sides of the lower component 200.

(48) To utilize the invention, the user inserts the front cap 300 and rear cap 400 into the lower component 200. The user utilizes the screws 500 to secure the lower component 200 to the front cap 300 and the rear cap 400. In some embodiments the front cap 300 and rear cap 400 are part of the lower component 200 rather than separate components. In other embodiments the front cap 300 and rear cap 400 are already attached to the lower component 200. The user then positions the lower component 200 against the lower receiver and inserts the barrel 24 into the lower component 200. The user ensures that the front cap top side 310 and rear cap top side 410 engages the barrel 24. The user then places the upper component 100 over the gas tube 22. The user inserts the tabs 110 of the upper component 100 into the slots 210 of the lower component 200. At this point in time the sights are zeroed. The user can fire the firearm 20. The user can then ensure that the sights are zeroed by confirming the location of a hit on a target

(49) Other embodiments are possible without varying from the core of the invention. For instance, the screws 500 may be any size and shape or may be replaced by other fastening members.
