The bolt includes a polymer spring that biases a sliding extractor against the base of a cartridge. The sliding extractor is disposed at an angle ranging from thirty degrees to fifteen degrees on the bolt face to provide a low ejection angle from the firearm.

Abstract: An improved magazine follower for use in existing magazines such as a 30 round magazine comprises a follower plate, a base plate, and a spring. The follower plate comprises a top plate, a convex follower leg, and a concave follower leg. The external shapes of the top plate, the convex follower leg, and the concave follower leg mirror the interior profile of the magazine, constraining the motion of the follower plate to a well-defined path within the magazine. The method of attaching the spring to the follower plate and the base plate in addition to the shape of the spring keeps the spring from “wobbling” or moving off a vertical axis of the spring as rounds of ammunition are loaded or dispensed. Consequently, the present system reduces binding or jams within the magazine, improving performance and life of the magazine follower.

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.
