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.

Abstract: The invention is an improved load bearing arrangement for use with firearms. The system comprises a cylindrical body with a sealing cap, mounting structure on the body including a plurality of mounting tabs and a “T” rail with matching structure on the stock. The mounting tabs are only partially fastened on the body so as to form hooks which will secure the body from behind the structure on the stock. The “T” rail interfaces with a corresponding notch on the rear of the stock and is secured with the stock's butt pad. A water-tight cap is also provided, which is also capable of removal and replacement without removing the remaining structure from the stock.
