10. The charging assembly for a firearm of claim 1, wherein said handle base portion comprises a handle element fastener aperture formed through at least a portion of said handle base portion, wherein when said handle projection is removably positioned within at least a portion of said at least one handle element aperture, said handle element fastener aperture is aligned with said charging bar fastener aperture of said charging bar, so as to allow a fastener to pass at least partially through said handle element fastener aperture and into said charging bar fastener aperture.

11. The charging assembly for a firearm of claim 1, wherein said handguard further comprises an engagement element positioned within said handguard so as to interact with said engagement finger, when said charging bar is in a locked or disengaged position to releasably maintain said charging bar in said locked or disengaged position.

12. A charging assembly for a firearm, comprising:

a charging bar, wherein a charging bar protrusion extends from said charging bar, proximate a second end of said charging bar, wherein a bolt carrier engaging shoulder is formed by said charging bar protrusion, wherein a gas tube aperture is formed through said charging bar protrusion, along a longitudinal axis of said charging bar, wherein a first charging bar channel is formed in said charging bar from a first end of said charging bar to said charging bar protrusion and wherein a second charging bar channel is formed in said charging bar from said charging bar protrusion to said second end, and wherein said gas tube aperture is formed so as to provide an aperture through said charging bar protrusion, between said first charging bar channel and said second charging bar channel, and wherein an engagement finger extends from said first end of said charging bar, and wherein at least one charging bar fastener aperture is formed through at least one of said side walls of said charging bar;
