    Abstract: A non-reciprocating, self-engaging charging handle is disclosed. It comprises a spring biased forward latch mounted upon a sliding body with a protruding handle. The spring bias causes the latch to positively engage the firearm's bolt carrier group when the handle is brought forward into contact therewith. A secondary latching system secures the charging handle to the upper receiver when not in use and disengages automatically when and only when a user desires to operate the handle.
