Abstract

A firearm includes a receiver and a bolt carrier disposed in the receiver. The bolt carrier is moveable between a firing position and a rearward position. A rod is fixed relative to the bolt carrier and a hand guard is coupled to the receiver about the rod. A handle assembly is slideably supported by the hand guard and is moveable toward the receiver to define a charging motion and away from the receiver to define a forward assist motion. The handle assembly receives the rod during both of the charging and forward assist motions. An arm is coupled to the base and is moveable between a disengaged position spaced from the rod and an engaged position abutting the rod. When the arm is in the engaged position, the handle assembly is moved to move the rod and the bolt carrier in either of the charging and the forward assist motions.

5. The firearm as set forth in claim 4 wherein one of said arm and said hand guard defines a notch and the other of said arm and said hand guard includes a projection nesting with said notch when said arm is rotated to said disengaged position for selectively retaining said handle assembly in position relative to said hand guard.

6. The firearm as set forth in claim 3 wherein said arm is slideably coupled to said base and is slideable relative to said base between said engaged position and said disengaged position.

7. The firearm as set forth in claim 3 wherein at least one of said hand guard and said base defines an indentation and the other of said hand guard and said base includes a detent selectively engageable with said indentation for retaining said handle assembly in position relative to said hand guard.

8. The firearm as set forth in claim 3 further comprising a spring coupled to said base and said arm for urging said arm toward said disengaged position.

9. The firearm as set forth in claim 1 wherein said base of said handle assembly includes a slider slideable along said hand guard and supporting said arm and a body connected to said slider and receiving said rod.

10. The firearm as set forth in claim 1 wherein said hand guard defines a slot extending substantially parallel to said longitudinal axis and wherein said handle assembly extends through said slot from an interior of said hand guard to an exterior of said hand guard.

11. The firearm as set forth in claim 1 wherein said hand guard defines a first slot and a second slot spaced from each other about said longitudinal axis and wherein said handle assembly extends through at least one of said slots from an interior of said hand guard to an exterior of said hand guard.

12. The firearm as set forth in claim 11 wherein said base slideably engages said hand guard and supports said arm and wherein at least one of said base and said arm extends simultaneously from said first slot and said second slot.

13. The firearm as set forth in claim 11 wherein said base of said handle assembly includes a slider slideable along said hand guard and supporting said arm and a body connected to said slider and receiving said rod and wherein said slider and said body are selectively arranged in a first configuration with said handle assembly extending from said hand guard only through said first slot and a second configuration with said handle assembly extending from said hand guard only through said second slot.

14. The firearm as set forth in claim 13 wherein said slider includes a first surface and a second surface spaced from each other with said body abutting said first surface in said first configuration and with said body abutting said second surface in said second configuration.

15. The firearm as set forth in claim 13 further comprising a pin supported by said slider with said pin engageable with said body and retaining said body to said slider when in either of said first and second configurations.

16. The firearm as set forth in claim 1 wherein said rod defines an annular groove with said arm abutting said rod in said annular groove when in said engaged position.

17. The firearm as set forth in claim 1 wherein said rod has a forward assist surface and a charging surface each extending transversely to said longitudinal axis and wherein said arm abuts said forward assist surface when moved into said engaged position and in said forward assist motion and wherein said handle assembly abuts said charging surface when moved into said engaged position and in said charging motion.

18. The firearm as set forth in claim 1 wherein said base of said handle assembly has a ledge extending into said base bore transversely to said longitudinal axis and wherein said rod includes a lip engaging said ledge when said handle assembly is moved in said charging motion.

19. A charging mechanism for a firearm, said charging mechanism comprising:

a bolt carrier extending along a longitudinal axis;

a rod fixed relative to said bolt carrier and extending substantially parallel said longitudinal axis and defining a recess extending transverse to said longitudinal axis; and

a handle assembly having a base defining a base bore receiving said rod substantially parallel to said longitudinal axis, said handle assembly being moveable with said rod in one direction along said longitudinal axis in a charging motion and in an opposite direction along said longitudinal axis in a forward assist motion;

said handle assembly engaging said rod during said charging motion for moving said bolt carrier toward a rearward position; and

said handle assembly having an arm supported by said base and being selectively moveable transversely to said longitudinal axis between a disengaged position spaced from said rod and an engaged position abutting said rod in said recess wherein said arm in said engaged position is fixed to said rod for moving said bolt carrier toward a firing position during movement of said handle assembly in said forward assist motion.
