Abstract: The present invention is an improved charging handle for a firearm. The handle is generally non-reciprocating and features a user activated forward assist. The major components are an actuator to provide charging function and upon which other components are mounted, a spring biased lever with a hook which biases downward so that the hook may interface a bolt carrier when the lever is activated, and a blade upon which handle structure is mounted. In the preferred embodiment, the handle is ambidextrous and features a spring detent to keep it in stowed position until the user desires use. The handle will only reciprocate when the lever is activated, which in turn requires intentional user action, thereby providing a relatively safer weapon to operate.

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.

Abstract: The present invention is a spring-biased folding firearm that stows compactly and safely. The firearm has three main components: a stock, a receiver and a grip/magazine combination. In folding, the stock folds over the receiver, sandwiching the grip/magazine between the components. When folded, the magazine over-inserts into the grip housing, allowing the stock to clear and providing additional safety when stowed by isolating the ammunition feed. A buttplate latches over the open joint to contain the unit and further secure it. When stowed, the bolt is disengaged from the ammunition feed supply, preventing accidental firing, so a loaded round can be safely carried in the chamber—allowing for immediate use of the firearm upon opening. The weapon is deployed through single-handed actuation and is spring-assisted into firing position. Currently the firearm uses readily available aftermarket parts for easier replacement if necessary and does contain hardware for mounting accessories.
