Abstract: An ammunition magazine for an automatic weapon wherein a spring-loaded con of successive cartridges are each fed in alignment to a firing chamber upon the reciprocating action of a bolt. The magazine has a pair of feed-gates, each of which is pivotally mounted on the magazine. The upper ends of the feed-gates together form a semi-circular, separably engaged, retaining cover for the top cartridge in the magazine. The lower ends of the feed-gates in sequence separably engage the next successive round in the magazine in response to the pivotal movement of the upper ends of both gates. This latter action keeps the successive round out of contact with the bolt while the top round is stripped and fed into the firing chamber by the bolt.

Abstract: A firearm magazine comprises an elongate container which has an end opening and is partitioned internally into two contiguous housings.

At their ends facing the opening, the housings open into an end portion of the container which also has a width that decreases gradually towards the opening. An elevator member is movable in the container under the action of resilient means to push the cartridges towards the opening. The bearing and thrust surfaces of the elevator member and the internal walls of the container are shaped so as to allow the removal of successive cartridges housed in the container without jamming, when in use in a firearm.

Abstract: A magazine for a rimfire adapter to feed cartridges into a rifle in which e cartridges are shorter than those for which the rifle was intended. The magazine cavity is positioned rearwardly, in order for the base of the shorter cartridges to be positioned longitudinally in the same position the original cartridge would have been if it were used. This overcomes the double firing safety hazard while suitable ramps and guides are positioned forwardly to guide cartridge travel forward to the chamber.

Abstract: A semi-automatic sporting rifle, firing high powered center fire cartridges, is easily and quickly convertible to a 22 rimfire rifle without loss of feel or balance. The dual purpose rifle features a short stroke, gas operating system which is rendered inactive when the rifle is converted to 22 rimfire action. In the conversion, a locking bolt assembly and magazine for high powered ammunition are replaced by a non-locking bolt and a combined cartridge adapter and magazine holder for 22 calibre rimfire ammunition. The principal components of the firearm, including barrel, receiver, firing mechanism, action spring, magazine latch, bolt connecting link, charging handle, sights, stock and forearm, are common to both forms of the rifle. The conversion may be accomplished by using only a pointed object, such as a bullet point or ball point pen.

Abstract: Disclosed is an ammunition magazine which may be made of plastic, pre-loaded with ammunition rounds and stored in the loaded condition for extended periods of time without deterioration. A spring motor is mounted on and drives an ammunition follower to urge the ammunition rounds toward the magazine's feed opening, and includes a drive gear which engages a gear rack formed on an interior wall of the magazine housing. The spring motor is disposed in an operationally unstressed condition during storage of the loaded magazine. To ready the magazine for use, a plastic strip having a gear rack formed thereon may be pulled from the bottom of the housing, thereby rotating an energizing gear which winds the spring motor to an operationally stressed condition.

For operation in one of the non-continuous modes, an indexing device disposed on the rear portion of a first lever in the firearm trigger mechanism is placed into engagement with an advancing mechanism carried by a second lever that selectively actuates the firearm operating rod. The advancing mechanism has a second indexing device engageable with a plate or other transport device slidably mounted on the second lever and engageable with a catch on the operating rod. When the continuous mode is selected, the indexing device on the second lever rests in an idling recess disposed on the rear portion of the first lever forwardly of the indexing device thereon. An improved cartridge magazine and cartridge construction suitable for use in such firearm, together with improved facilities for operating the breech section of such firearm, are also described.
