An ambidextrous charging handle for a Stoner-type firearm. The charging
handle comprises two separate assemblies, these being an oblong handle
that contains a latch assembly and a central shaft member. The parts are
joined together by a compound pivoting arrangement in which a combination
of the latch assembly and alignment grooves in the central shaft member
interacting with slidingly engage a locating flange on the oblong handle,
and a pair of pivoting connectors that secure the latch assembly to the
oblong handle and the central shaft member independently from one
another. The latch assembly includes cam activation via a retention
relief cut acting against a fixed minor pivot connector. The second point
of retention for the assembly is via a major pivoting connector the
combination of which transmits the retraction force applied to the oblong
handle on one end of the latch assembly and to the central shaft member
through the interconnection of the minor pivot connector located at the
proximal end of the latch body.
