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.

Dependent claims

A firearm comprising:

a receiver defining a receiver bore extending along a longitudinal axis;
a bolt carrier disposed in said receiver bore and moveable relative to said receiver along said longitudinal axis between a firing position and a rearward position;
an elongated member fixed relative to said bolt carrier and extending substantially parallel to said longitudinal axis;
a hand guard coupled to said receiver and disposed about said elongated member;
and
a handle assembly disposed in said hand guard and moveable toward said receiver to define a charging motion and away from said receiver to define a forward assist motion with said handle assembly engaging said elongated member during both of said charging motion and said forward assist motion, said handle assembly including:
a base disposed in said hand guard;
and
an arm coupled to said base and moveable between a disengaged position spaced from said elongated member and an engaged position abutting said elongated member with said arm moving said elongated member and said bolt carrier toward said firing position when in said engaged position and when said handle assembly is moved in said forward assist motion and with said arm moving said elongated member and said bolt carrier toward said rearward position when in said engaged position and when said handle assembly is moved in said charging motion.

6 more elements

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

a bolt carrier extending along a longitudinal axis;
an elongated member 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 and being moveable with said elongated member 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 elongated member 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 elongated member and an engaged position abutting said elongated member in said recess wherein said arm in said engaged position is fixed to said elongated member for moving said bolt carrier toward a firing position during movement of said handle assembly in said forward assist motion and toward a rearward position during movement of said handle assembly in said charging motion.
