Losok Valkyr Rifle

Abstract

The current invention is a semi-automatic rifle, of the detachable magazine fed, air cooled, gas driven type. The rifle uses some parts from The M1 Garand Rifle U.S. Pat. No. 1,892,141, but differs in method of feeding, bolt operation, barrel design, receiver design, sight systems, and gas system design, therefore requiring a new patent application. The rifle solves shortcomings of the M1 rifle by the upgrading of the listed functions to enhance the rifle's use for the modern shooter.

1 . The rifle consists of multiple parts groups that work and function together to allow the operation of the rifle as a whole. The receiver group consists of the receiver housing which is the receiver, and its small parts such as bolt stops, and various pins to mount other groups to the receiver which is the heart of the rifle. The bolt group, consists of the bolt, its internal parts the firing pin, firing pin spring, ejector and spring, and the extractor and spring. The barrel group consists of the barrel and the gas system parts, the gas cylinder, operating rod, rod guide and spring and gas piston the barrel may also attach a muzzle device. The stock group consists of the stock, with fixed or adjustable butt stocks, and the hand guard which mounts to the stock with no contact on the barrel. The trigger group consists of the trigger housing and its internal parts which include the trigger, sear, safety, associated pins and the hammer, along with a trigger guard. The magazine group is the magazine housing, the follower, the spring and the floorplate. 
     
     
         2 . The receiver listed in claim one  1  above to consist of a machined, cast, forged or other method of manufacture part of steel aluminum, polymer or other material part heat treated and finished by appropriate means. The part is designed to house a bolt group also used in the US M1 Rifle or of identical specification dimensions part or one of similar design of varying size. Part shall mount a barrel via any normal means such as threading, pinning or pressing. The part shall attach the rifle to the stock by working with the trigger group and other means as needed. The receiver to accept optical sight attachment at various points on the top and side of the receiver. The receiver to incorporate bolt stop activated by the magazine and mounted on the receiver its self and acting on the bolt. The receiver will also mount the points of the attachment for the operating rod, operating rod spring guide and trigger housing. The magazine well to be an integral part of the receiver not a separate part, and to also act as a recoil lug and location point for the receiver in the stock. The receiver can be made in various sized versions to accommodate larger or smaller cartridges. 
     
     
         3 . The bolt group of claim one above can be either a USGI M1 Garand bolt and its component parts such as the firing pin and spring, extractor and spring, and ejector and spring, or a new manufacture part of the same design and dimensions for standard cartridges or of various sized versions with parts of the similar design to the USGI part for other size cartridges. The part to be cast, forged, machined or otherwise manufactured of appropriate materials heat treated or otherwise finished for suitable performance. The bolt to attach to the operating rod and gas system in the same manner as the M1 rifle, but to engage a bolt stop in the receiver housing itself, not like the M1 rifle. 
     
     
         4 . The Barrel Group of  claim 1  Above to consist of the barrel and gas system. The barrel to be made of steel or other material by any accepted means with rifling grooves cut by any industry accepted means to give acceptable performance. The barrel will be threaded and have a breech of the same design as the M1 rifle, but will differ in the method of stabilization and attachment to the stock and will not attach to the hand guard in any way. The barrel may mount a muzzle device as needed by a variety of means. The gas system to be mounted to the barrel by means of a pin and shoulder system with no spline cuts or other means as used in the M1 Rifle, and with much lower mounting level to facilitate the use of a straight operating rod. The operating rod and gas piston assembly to be of a much shorter and now straight type as opposed to the M1 type. The design of the this system to achieve a much improved capacity to handle higher pressures experienced by larger cartridges slower burning powders. The design of the system also eliminates the need to bend each rod in a very complex manner, and allows the use of shorter barrels. The length of the operating rod can be varied easily to accommodate any length desired or required to attain optimal operation with virtually any rifle configuration or caliber. The system to feature a gas plug that will allow the adjustable flow of gas back to the piston on the operating rod tip, to slow down or speed up the operation of the action of the rifle to obtain the best accuracy and reliability dependent on the caliber and conditions the rifle is to used in. The operating rod guide to be a of a straight type mounting to the receiver group and sized to fit the rod and spring to ensure the smooth straight flow of the operating rod and spring in all conditions. All parts of the gas system to be manufactured of steel or other suitable material by machining, forging, turning, casting and heat treated as need to enhance performance. 
     
     
         5 . The stock group of claim one above to consist of a stock and hand guard system with either a conventional configuration butt stock or an collapsible version with an attached pistol grip. The stock can be made of any material, but shall have the following unique features. The stock to be designed to work with the magazine well design of the receiver in group one to locate the rifle in the stock by means of multiple surfaces on the magazine well acting as recoil lugs and the magazine well also functioning as a square pillar to locate the receiver and attached parts in the same position upon removal and reinsertion in the stock. The hand guard to mount to the stock only with no contact on the barrel in any position, the hand guard to feature adjustment in height to accommodate varying barrel diameters, and optic heights. The hand guard to mount an optical rail to facilitate the mounting of optics as needed at the 12, 3, and 9 clock positions. The stock and hand guard can be made to varying sizes to accommodate up or downsized rifles as needed. 
     
     
         6 . The trigger group of  claim 1  above to consist of a unique housing to locate internal parts of US M1 Rifle trigger group so that they will function in the rifle as originally designed, but also to secure the new rifle and magazine group in the newly designed stock. The housing to differ from the M1 Rifle in that the magazine release and other parts needed to function with a detachable box magazine have been designed in. The magazine release to be a spring driven part to engage the magazine and lock it in place with a convenient tab to release when needed. The new housing to be in contact with the magazine well along both sides. The housing to be made by machining, casting, forging, or other means from steel or other suitable material finished and heat treated as needed. 
     
     
         7 . The Magazine group of  claim 1  above to consist of steel or other suitable material box magazine sized to hold the desired cartridges of the receiver being used. The magazine consisting of the housing and its spring follower and floor plate. The magazine will fit the magazine well and insert from the bottom as opposed to the en bloc clip of the M1 rifle. The magazine can vary in capacity depending on use. The magazine to work with the trigger housing and group by fitting into position in the magazine well and stock and locking into place by means of a tab or similar protrusion or stop on the rear of the magazine that engages the release on the trigger housing.
