1. A free-floating handguard for a rifle comprising: a generally cylindrical body including a first end portion and an opposed second end portion;an integral top firearm accessory mounting rail located along the top portion of the body;a left longitudinal section extending from the left of the cylindrical body configured to support a removable firearm accessory mounting rail section;a right longitudinal section extending from the right of the cylindrical body configured to support a removable firearm accessory mounting rail section;a bottom longitudinal section extending from the bottom of the cylindrical body configured to support a removable firearm accessory mounting rail section;wherein each of the left, right, and bottom longitudinal sections have a curved cross-sectional profile having a radius of curvature that is greater than the outside radius of the cylindrical body; andwherein the left and right longitudinal sections are oriented within a circle defined by the less of the radius of curvature of either the left or right longitudinal sections centered about a central axis of the cylindrical body. 2. The handguard of claim 1, wherein the radius of curvature of the left and right longitudinal sections is between 1.0 to 1.5 inches and the radius of the cylindrical body is between 0.5 and 1.0 inches and wherein the left and right longitudinal sections have substantially the same radius of curvature. 3. The handguard of claim 1, wherein the body portion includes a single piece unitary construction. 4. The handguard of claim 1, further comprising longitudinal channels located on the inside portion of the cylindrical body opposite at least one of the longitudinal sections, wherein the channels are configured to receive slide nuts. 5. The handguard of claim 4, wherein the slide nuts include at least spaced apart threaded apertures and wherein the spacing between the threaded apertures corresponds to spacing between at least one pair of apertures in the longitudinal section. 6. The handguard of claim 4, wherein the channels are configured to retain the slide nuts in the radial direction and allow the slide nuts to slide axially. 7. The handguard of claim 1, wherein the body includes threaded inserts configured to secure modular firearm accessory mounting rail sections. 8. The handguard of claim 1, wherein each of the left, right, or bottom longitudinal sections includes apertures for receiving shear lugs of the removable firearm accessory mounting rail sections. 9. The handguard of claim 8, wherein between the apertures for receiving shear lugs are apertures that receive screws that connect the removable firearm accessory mounting rail sections to the longitudinal sections and wherein each aperture for receiving shear lugs is configured to receive a pair of shear lugs. 10. The handguard of claim 9, further comprising removable firearm accessory mounting rail sections secured to at least one of the left, right, or bottom longitudinal sections. 11. A free-floating handguard for a rifle comprising: a generally cylindrical body including a first end portion and an opposed second end portion;an integral top rail located along the top portion of the body;a left longitudinal section extending from a left of the cylindrical body configured to support a removable firearm accessory mounting rail section;a right longitudinal section extending from the right of the cylindrical body configured to support a removable firearm accessory mounting rail section;a bottom longitudinal section extending from the bottom of the cylindrical body configured to support a removable firearm accessory mounting rail section;an internal longitudinal channel configured to receive a slide nut;a slide nut received in the longitudinal channel, the slide nut including at least two spaced apart threaded apertures;a removable rail section secured adjacent to one of the left, right, or bottom longitudinal sections;at least two threaded fasteners that extend through the removable firearm accessory mounting rail section and at least a portion of the slide nut; anda shear lug that extends from the removable firearm accessory mounting rail section through at least a portion of the left, right, or bottom longitudinal sections. 12. The handguard of claim 11, wherein each of the left, right, and bottom longitudinal sections have a curved cross-sectional profile having a radius of curvature that is greater than the radius of the cylindrical body. 13. The handguard of claim 11, further comprising a first, second, and third aperture in the left, right, or bottom longitudinal sections, wherein the second aperture is between the first and third apertures and is configured to receive shear lugs, and the first and third apertures are configured to receive threaded fasteners. 14. The handguard of claim 13, wherein the second aperture is configured to receive a pair of spaced apart shear lugs. 15. The handguard of claim 11, wherein the cylindrical body portion includes a single piece unitary construction. 16. A method of connecting a rail based weapon accessory to a rifle comprising: aligning an upper firearm accessory mounting rail of the handguard with a rifle receiver;clamping a first end of the handguard to a barrel nut;sliding a slide nut down a channel in the handguard;aligning a first aperture in the slide nut with a first aperture of the removable firearm accessory mounting rail section thereby simultaneous aligning a second aperture in the slide nut with a second aperture of the removable firearm accessory mounting rail section;threading a first screw through the first aperture of the removable firearm accessory mounting rail and at least a portion of the first aperture of the slide nut;threading a second screw through the second aperture of the removable firearm accessory mounting rail and at least a portion of the second aperture of the slide nut; andwherein the threading steps are accomplished without manually holding onto the slide nut. 17. The method of claim 16, further comprising attaching a rail based weapon accessory to the removable firearm accessory mounting rail section. 18. The method of claim 16, wherein the step of aligning the handguard with the rifle includes aligning a longitudinal firearm accessory mounting rail on the top side of the handguard with a firearm accessory mounting rail section on the receiver. 19. The method of claim 16, wherein the step of aligning the first aperture in the slide nut with a first aperture in the removable firearm accessory mounting rails simultaneously aligns a third aperture in the rail with a third aperture of the slide nut. 20. The method of claim 16, wherein the threading step includes rotating the screw while the slide nut is positioned within the channel such that rotation and radial movement is limited.
