DETAILED DESCRIPTION

U.S. Provisional Application No. 61/926,161 titled “A significant improvement to the standard M14 rifle receiver” and filed 10 Jan. 2014 in the name of the same inventor as this non-provisional application is hereby incorporated by reference as if fully set forth herein.
Current M14 rifles include receivers that require multiple parts to be assembled on the receiver in order for a scope to be properly and securely mounted. (The receiver is the portion of a rifle that houses at least some of the rifle's operating components, for example a bolt carrier group, trigger group, and magazine port.) In most cases, the parts required to be assembled include a scope mount, a left side receiver screw, two screws in a stripper clip dove tail, and one or two screws on a forward portion of the receiver above the barrel. The screws hold the scope mount in place.
Current mounts and associated parts are typically made either of aluminum or steel. The quality of each part is varied depending on where the part is manufactured. Each of the parts may shift or otherwise move out of alignment. As one result, the probability of misalignment of attached optics may increase with every shot taken with the rifle. At ranges exceeding 1,000 meters, this misalignment may be significantly compounded. Thus, the current arrangement provides an inconsistent rifle platform. Other platforms besides the M14 also suffer from these issues.
A rifle receiver according to aspects of the subject technology addresses the foregoing issue by including a housing for operating parts of the rifle and an integral scope mount. The scope mount may be integral by virtue of having been cast as part of the receiver, machined as part of the receiver, welded to the receiver, or otherwise affixed as an integral part of the receiver. This arrangement may greatly reduce or even eliminate the possibility of optic misalignment and the probability of additional parts moving. The arrangement may also significantly increase the simplicity of mounting optics onto the receiver, improve the rigidity and accuracy of a rifle that includes the receiver, and/or increase the reliability of the platform in a variety of environments.
The scope mount may be a picatinny rail, a weaver rail, or some other form of mount, base, or rail. Although the term “scope mount” is used in this disclosure, devices other than scopes, for example low-light optics, range finders, lights, and the like, may also be mounted on the scope mount. Iron sights may be included or omitted. The scope mount may have 0 MOA, 20 MOA, or any other MOA. (MOA is moments of angle—a measure of the angle between the scope mount and a barrel mounted in the receiver)
FIG. 1 illustrates a perspective view of a first rifle receiver configured in the above-described manner. The figure shows receiver 10 including housing 12 for operating components of a rifle.
According to aspects of the subject technology, receiver 10 also includes integral scope mount 14. The illustrated scope mount is a picatinny rail. Other types of scope mounts may be used, for example but not limited to a weaver rail.
Preferable, the scope mount is integral with the housing by virtue of having been cast or machined as part of the receiver when the receiver was manufactured. Alternatively, the scope mount may be attached to an existing receiver in some suitably durable fashion, for example but not limited to being welded to the housing.
FIGS. 2, 3, and 4 shows different views of the receiver shown in FIG. 1.
FIG. 5 illustrates a perspective view of a second rifle receiver according to aspects of the subject technology. Receiver 50 in FIG. 5 includes housing 52 with extended integral scope mount 54. The housing also has a larger ejection port 56, for example to accommodate larger caliber rounds than receiver 10 in FIGS. 1, 2, 3, and 4.
Some possible details of contemplated commercial embodiments and possible variations of a rifle that includes a receiver according to aspects of the subject technology follow. Some explanatory and/or marking information also is included. The invention is not limited to the details of these embodiments, possible variations, explanatory information, and marketing information.
M35A1: A rifle using a receiver based on an M14 rifle platform designed as a Designated Marksman Rifle. Features may include:

- Integral 7.5″ long picatinny mount
- 20 MOA (minutes of angle) picatinny rail
- Stronger receiver
- Greater accuracy
- CNC machined from 8620 steel billet
- Mil-spec heat treated and phosphate finished
- Accepts all commercial or military semi-automatic components

M35M1: An M35A1 modified to redesign the bolt for a large case, the box magazines for a wider case body, and the barrel threads for a new match barrel machined to the 300 RUSAM (.300 Remington Ultra Short Action Magnum) dimensions.
The gas system, operating rod, scope base and other components may not necessarily need to be changed. The advantages of this combination are, first, the currently military training on the use and maintenance of the M14 can be immediately applied to the M35M1, second, the military already has component parts and accessories in stock, and third, the increase in weight may lead to better accuracy and longevity.
M35M2: The receiver includes an increased receiver length around the barrels threads from one inch to two inches. This is to increase the strength of the attachment point of the barrel and receiver. This may also decrease the harmonic vibration that impairs accuracy. The result of the M2 improvements may provide a greater effective range of the platform and cartridge.
M34A1: The receiver is designed to meet the majority of commercial requirements for an all-around effective battle rifle platform. The M34A1 retains the standard iron sights from the original M14 but includes the integral picatinny scope base of the M35 series. The picatinny rail is machined at 0 MOA to allow for use from 0 to 1000 m. The rails system may take all the standard optics and accessories to meet the customer's requirements. The optimal barrel length for the M34A1 may be the 18″ barrel as used on the scout rifle platforms. This may allow the user a shorter rifle than the current M14 or M35 to be used in close quarter conditions but still retain the solid scope base for any long range engagements out to 1000 m.
Mini-34A1: The receiver will actually be smaller rather than larger. The commercial demand may be for a shorter platform with a smaller cartridge. Primarily designed as an upgrade of the famous Ruger Mini-14.
Mini-35: The receiver is designed as a “scope only” model for use with a heavy varmint barrel and chambered for a variety of cartridges.
Mini-34ARC: A standard Mini-34 receiver with traditional iron sights improved by the addition of an integral picatinny rail and mated to an SR 556 barrel and piston assembly. This design addresses poor characteristics that have plagued the Mini-14 from inception. The number one problem was the small outside diameter barrel which came in only one length. The thin barrel flexed too much for most long range accurate shooters. The number two problem was the poor gas system. It worked but was required to be completely disassembled to be cleaned properly and once re-assembled the point of aim had to be re-established.
The Mini-34ARC would have an AR style barrel usually produced in heavy contour and in a variety of lengths from pistol length of 10″ to the ultimate varmint rifle length of 26″. The second benefit would be the gas system. This is a robust system designed for maximum use and requires very little maintenance or complete disassembly for cleaning The rifle combination may weigh more than the original Mini-14 but may exhibit significantly improved reliability and accuracy.
M-134 Carbine: A receiver based off of the M-1 Carbine receiver. The receiver may be configured for various cartridges, including but not limited to standard 30 Carbine, 9MM, 40 S&W, 10MM, 45ACP, 45 Winchester Magnum, 38 Special, 357 Magnum, 41 Magnum, 44 Special, and 44 Magnum.
M-34/240MF and the Mini-34/249MF: Off-shoots of the M34M2 platform but with inter-changeable barrels. The extended receiver length may allow this unique design feature of using standard military specification barrel assemblies from M240 and M249 SAWs.
M-34/240 and Mini-34/249: Belt-fed versions.
M-144: Based on the M-1 Garand receiver/platform including iron sights.
M-145: Based on the M-1 Garand receiver/platform, but not including iron sights.
Note: In the foregoing, the “M” designation indicates 2″ barrel threads as opposed to the shorter threads in a standard AR-14 receiver. Other size barrel threads may be used.
