Publication number: 20090277066Abstract: 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.Type: ApplicationFiled: April 7, 2009Publication date: November 12, 2009Applicant: MAGPUL INDUSTRIES CORPInventors: Eric C.
