As discussed above, embodiments of the present invention relate to an upper receiver with a side charging handle for an AR style rifle or similar weapon.
Referring to the drawings, FIGS. 1 and 2 depict a rifle 10 with the conversion kit 12 coupled there to. The rifle 10 comprises a lower receiver 13, wherein the lower receiver is coupled to a pistol grip 16, a butt stock 18, a trigger 28 a magazine 20 and all other components that are conventionally part of an AR style rifle. The rifle 10 further comprises an upper receiver 14, wherein the upper receiver is coupled to a barrel 26, and a hand guard 22. A bolt carrier and bolt are operationally coupled within the upper receiver 14. According to embodiments of the present invention, the lower receiver 13 is operatively coupled with the upper receiver 14 by use of two pins, wherein the two pins comprise a front pin 15 and a rear pin 17. The coupling of the lower receiver 13 to the upper receiver 14 results in a mechanical coupling of all of the interior operational components located within the lower receiver and the bolt carrier 30 of the upper receiver 14. All of the components are operationally assembled together.
It will be understood that the lower receiver 13, the butt stock 18, the trigger 28, the hand guard 22, pistol grip 16, and the barrel 26 and all other external and internal components not specifically discussed are assembled in an AR style rifle, and are part of the rifle 10. The upper receiver assembly 14 of the rifle 10 includes other conventional parts that are not specifically discussed in this disclosure and therefor in at least this way, the upper receiver assembly 14 may fully replace a conventional upper receiver assembly of an AR style.
With additional reference to FIGS. 3-16, the upper receiver assembly 14 includes an upper receiver body 40 with a channel 42 formed in a side of the body 40.
