3. The rifle as in claim 2 , wherein the upper hand guard and the lower hand guard are releaseably secured to the upper receiver by a collar.
4. The rifle as in claim 1 , wherein the upper hand guard and the lower hand guard are releaseably secured to the upper receiver by a collar.
5. The rifle as in claim 1 , wherein the rifle further comprises: an indirect gas operating system having a gas block and a movable piston located outside of the upper receiver, the gas block being coupled to the barrel of the rifle and in fluid communication with the barrel, the movable piston in communication with the gas block.
6. The rifle as in claim 5 , wherein the piston is removable from a front of the gas block of the rifle without disassembly of the gas block from the rifle and wherein the gas block has a foldable sight mounted thereon.
7. The rifle as in claim 1 , wherein the lower hand guard has a six o'clock rail with respect to the barrel of the rifle and wherein the upper rail of the upper hand guard is a twelve o'clock rail with respect to the barrel of the rifle.
8. The rifle as in claim 1 , wherein the upper rail of the upper hand guard extends completely along the rear tab of the upper hand guard.
9. A method for removably securing a hand guard to a semi-automatic or automatic rifle, the method comprising:
removably coupling a rear end of an upper hand guard to an upper receiver of the rifle;
removably coupling a rear end of a lower hand guard to an upper receiver of the rifle;
removably coupling a forward end of the upper hand guard and a forward end of a lower hand guard to a cap, wherein the upper hand guard and the lower hand guard are not directly secured to a barrel of the rifle such that the upper hand guard and the lower hand guard float in position relative to the barrel of the rifle and wherein the upper hand guard has an integral upper rail that extends along an upper surface of the upper hand guard and the upper hand guard has a rear tab that is received within a mating slot of the upper receiver when the upper hand guard is secured to the upper receiver and wherein the upper rail of the upper hand guard is contiguous with a receiver rail when the upper hand guard is secured to the upper receiver.
10. The method as in claim 9 , wherein cap is secured to the forward end of the upper hand guard and the forward end of the lower hand guard with a plurality of pins.
11. The method as in claim 10 , wherein the upper hand guard and the lower hand guard are releaseably secured to the upper receiver by a collar.
12. The method as in claim 9 , wherein the upper hand guard and the lower hand guard are releaseably secured to the upper receiver by a collar.
13. The method as in claim 9 , wherein the rifle further comprises: an indirect gas operating system having a gas block and a movable piston located outside of the upper receiver, the gas block being coupled to the barrel of the rifle and in fluid communication with the barrel, the movable piston in communication with the gas block.
14. The method as in claim 13 , wherein the piston is removable from a front of the gas block of the rifle without disassembly of the gas block from the rifle and wherein the gas block has a foldable sight mounted thereon.
15. The method as in claim 9 , wherein the lower hand guard has a six o'clock rail with respect to the barrel of the rifle and wherein the upper rail of the upper hand guard is a twelve o'clock rail with respect to the barrel of the rifle.
16. The method as in claim 9 , wherein the upper rail of the upper hand guard extends completely along the rear tab of the upper hand guard.
17. The method as in claim 16 , wherein the lower hand guard has a six o'clock rail with respect to the barrel of the rifle and wherein the upper rail of the upper hand guard is a twelve o'clock rail with respect to the barrel of the rifle.
