Embodiments of the disclosure relate to semi-automatic, automatic, and bolt-action firearms and components for such firearms.

The present invention provides a system for autonomously conveying and loading a shell into a fixed gun, the system including an autonomous conveyance device configured to autonomously travel and move according to an autonomous driving program from a shell storage location to a fixed gun fixed to a gun mount that is a destination, an automatic loading device configured to hold a testing shell and automatically load the testing shell into a cartridge chamber of the fixed gun, and a shell lifting device mounted on an upper surface of the autonomous conveyance device and a lower surface of the automatic loading device and configured to move the automatic loading device upward or downward. According to the present invention, a process of conveying and loading the shell into the testing fixed gun may be autonomously performed in an unmanned manner.

A sub-mass projectile for a standard, unmodified firearm, comprising a core formed from a malleable core material with at least a portion of the core material being a non-metal material. The core has a lower mass than a standard projectile for the standard, unmodified firearm. An outer surface associated with the core has a diameter that is sized less than an outer diameter of a standard cartridge and larger than an inner diameter of a standard, unmodified barrel bore of the standard, unmodified firearm such that the outer surface associated with the core contacts the inner diameter of the standard, unmodified barrel bore to generate forces in the firearm that approximate operational forces of a standard mass projectile on the standard, unmodified firearm during operation.

A bolt catch device is disclosed. The bolt catch includes a movable surface configured to be positioned within a weapon so as to conditionally engage a bolt so as to prevent the bolt from rechambering a next round from a magazine, a tip configured to, in response to a received force, cause the movable surface to move so as to release the bolt, and a spring engagement feature configured to be positioned within the weapon so as to receive a spring within the weapon, wherein the spring within the weapon is configured to bias the movable surface toward a position which prevents the bolt from rechambering a next round.

An intrinsically safe firearm may include a handle and a frame connected by a pivot pin. One or more latches of the firearm can temporarily fix the firearm in a stowed orientation or a deployed orientation. In the deployed orientation, a magazine of the firearm can be removed from the handle; a slide of the firearm can be removed from the frame; a magazine safety allows a firing pin to strike a primer of a round in the firearm; and a trigger of the firearm is accessible to discharge the round in the firearm. In the stowed orientation, the magazine is not removable from the handle; the slide is not removable from the frame; the magazine safety prevents the firing pin from striking the primer; and the trigger of the firearm is not accessible.

An improved, projectile launching system that carries the bulk of its weight and ammunition in a mechanical backpack called Turtle. Turtle can be scaled up to carry much larger rounds like torpedoes or artillery shells, for submarines and artillery. The GUN can be scaled up as well.
