Abstract: Embodiments are directed toward a charging handle for a firearm. The charging handle preferably has a base, a shaft, a latch, and left and right levers pivotably coupled to the base by respective pivot pins and configured to disengage the latch from an upper receiver. The base preferably defines four substantially vertical mating surfaces. The entirety of each of the first and third mating surfaces contacts the left lever when pulled rearward. The entirety of each of the second and third mating surfaces contacts the right lever when pulled rearward. The third mating surface is preferably disposed at an acute angle to the first mating surface as measured forward and outward from the third mating surface. The fourth mating surface is preferably disposed at an acute angle to the second mating surface as measured forward and outward from the fourth mating surface. Accordingly, stress on the pivot pins is relieved.

Abstract: An aftermarket handguard system is described for use with an assault rifle, such as an AR-15. The system includes an elongated arcuate upper handguard section substantially defining a longitudinal axis and a plurality of radial planes normal thereto. The handguard section has left and right generally outward directed rail flanges having non-parallel flange mating surfaces. Two lower arcuate handguard sections are provided also each having laterally extending rail flanges with non-parallel flange mating surfaces. Three “T” shaped accessory rails each having a dovetail shaped portion are provided for mating to the non-parallel flange mating surfaces. Accessories may be mounted on the accessory rails in the conventional manner.
