The invention relates to handguns and is the firearm has the shorter length compared to systems in which the magazine is located in front of the trigger guard. Besides, the proposed firearm has the ability to quickly disassemble into the main components, which significantly reduces the dimensions of the firearm in the transport position. In addition, the magazine is also protected from loss when moving with the assembled firearm.

These results are achieved by the fact that the magazine of the firearm is located above the trigger guard, while access to the magazine is carried out only when the firearm is opened by turning the upper part of the receiver relative to its lower part. At the same time, the upper part of the receiver can be easily detached from its lower part to reduce the dimensions of the firearm during transportation.

The invention relates to firearms (mainly sports and hunting) and is a magazine-fed firearm in which the magazine is located behind the trigger and at the angle to the vertical plane. This solution allows to reduce the length of the firearm, while not complicating the process of installing the magazine.

A self-loading shotgun includes a lock movable inside a lock housing between an open position and a closed position, a barrel, a magazine disposed below the barrel, a lock catch for holding the lock in the open position, and a feeder system for lifting a cartridge delivered from the magazine to the height of the barrel. The feeder system includes a feeder that swivels about a transverse axis and a magazine hatch that interacts with the lock catch. To allow the self-loading shotgun to be fully loaded even when the lock is open, the swivel movement of the feeder generated by the lock is controlled by a control element separate from the lock catch.

A rotating bolt firearm may be configured to fire a .308 cartridge. However, the firearm may have a reduced weight in comparison to standard .308 rifles. The firearm may have many components typically used in a .223 rifle. The firearm may include a barrel extension with an extractor gap, which allows a .308 bolt to fit within a .223 sized barrel extension. The firearm may comprise an elongated magazine well in comparison to a .223 mil-spec rifle. The firearm may weigh less than 6.8 pounds with a 16-inch barrel, or less than 6.3 pounds with a 10.5 inch barrel.

A bracket for retaining a disassembled rifle preferably includes a retention bracket and a pair of retractable spring pins. The retention bracket includes a base plate, a first yoke, a second yoke, a first lug and a second lug. The two lugs and the two yokes extend upward from a top of the base plate. A width of the lug slot is sized to receive a lug projection of an upper receiver half of a rifle. The two retractable spring pins are retained in the first and second yokes. The first and second lug holes are sized to receive a spring pin of a lower receiver half of a rifle. A second embodiment of the rifle bracket includes a retention bracket with yokes that extend from a side of a base plate and two lugs that extend from an opposing side of the base plate.

A dual upper receiver for use with a firearm is provided. The dual upper receiver includes a first receiver portion; and a second receiver portion coupled to the first receiver portion. The first receiver portion is configured to couple to a first barrel, a first lower receiver and a first buttstock. The second receiver portion is configured to couple to a second barrel, a second lower receiver and a second buttstock. In embodiments, the dual upper receiver is formed as a unitary body. The dual upper receiver as a unitary body may include the first receiver portion and the second receiver portion are formed from a same piece of material.
