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.

Description
BACKGROUND OF THE INVENTION
[0001] The US Rifle M1 or M1 Garand Rifle was the main battle rifle
of the US from 1936 to 1957. The rifle while advanced for the time
was lacking in some areas that are now addressed by the invention
in this application. The gas operating system employed on the M1
utilized an operating rod nearly as long as the barrel and gas
cylinder that mounted very close to the barrel, for the rifle to
work, the rod had to be bent in a manner to clear the stock. The
bends in the rod and its length made it a fragile system not able
to withstand pressures used in more modern ammunition or higher
pressure calibers. The gas system also could not be adjusted to
facilitate use of other ammunition, or to adjust to varying
climates of use or to tune the rifle for better accuracy or
reliability. The M1 rifle also fed from 8 round en bloc clips fed
from the top of the rifle, requiring optics to be mounted on the
side, and limiting magazine capacity to 8 rounds. The rifle also
used an indirect bolt stop mechanism that acted on the operation
rod, not the bolt itself. The design of the stock on the M1 rifle
used two hand guards to cover the barrel and operating rod nearly
to the muzzle, limiting barrel diameter, and preventing a free
floating barrel/gas system. Rifles of similar design have usually
suffered from similar limitations or multi moving part gas systems.
Others have also been limited to short action rifle rounds of
limited power and versatility. What is needed is a rifle comparable
in simplicity to the M1 rifle with all its good qualities and
rugged reliability when used as designed, but able to handle higher
pressure loads, long action calibers, modern optics, and free float
barrel groups for enhanced accuracy, while having available
multiple barrel lengths and configurations.
SUMMARY OF THE INVENTION
[0002] The current invention while similar to the M1 rifle differs
enough to require a new patent application. The new invention
utilizes a short, straight operating rod with piston attached
directly to the rod, this type of system has fewer moving parts
than other short stroke systems, and uses a gas cylinder with
adjustable gas plug that is mounted and located on the bottom of
the barrel by a simple pin and shoulder arrangement rather than a
complicated spline cut set up. The gas feeds from the barrel to the
cylinder via port drilled in the bottom of the barrel. The simple
arrangement allows barrels and op-rods to be made to custom lengths
and configurations as needed for various calibers and specialty
users. The M1 rifle used an open top receiver design that loaded
from the top, the new rifle is a closed top design that mounts
optics on the integral rails at 12 and 9 clock positions (when
viewed from the rear), and with detachable box magazine feeding
from the bottom of the rifle. The receiver also mounts the bolt
stop which is activated by the magazine follower upon firing the
last round and released by a button on the exterior of the
receiver, as opposed to the M1 rifle where it acted on the
operating rod. The stock group of the current invention combined
with the trigger group and receiver with integral magazine well
serve to provide a free floating barrel and gas system for improved
accuracy and reliability and forward optics mounting by the height
adjustable hand guard with optics rail. The operation of the action
of the current invention is also enhanced by the closely fitted
operating rod guide and spring of a new design as compared to the
M1 rifle which coupled with the straight operating rod provides
smoother more accurate operation in all climates.

DETAILED DESCRIPTION OF THE INVENTION
[0017] The invention is an improved Semi-Automatic Rifle with
consisting of a Receiver group, Barrel Group, Bolt Group, Stock
Group, Trigger Group, and Magazine Group. The Invention is designed
to eliminate many of the issues that have been found in rifles like
the US M1 Rifle, U.S. Pat. No. 1,892,141 and similar rifles such as
weak gas systems, limitations pressure and caliber, limitations on
barrel diameter and length, poor feeding designs, no adjustable gas
system, poor optics mounting systems, week stock mounting points
with lack of return to zero upon re-installation in the stock. The
current invention addresses these through multiple simple changes
and additions to the basic art of the semi-automatic rifle in a
unique combination of parts in one rifle.
[0018] The part depicted in FIG. 1-4 is the receiver in the
stripped configuration with no parts such as the bolt stop in place
so to show the full extent of its design from four angles. The part
is to be made of steel or other suitable material, by casting,
forging, other methods. Proper heat treatment and surface
preparation will be needed to ensure proper operation and enhance
the toughness of the part.
[0019] The part in FIGS. 5 and 5A is the bolt group, this one of
standard US M1 rifle size and origin while other sizes and
configuration are to be available this is to be the most common
size and configuration. The part to be made of steel or other
material, and produced by casting forging, or the method with
properties required to be similar to 8620 steel hardened to
55-59HRC to insure toughness and long wear.
[0020] The parts in FIGS. 6 through 6C. Comprise the barrel group
and gas system. It is shown in only one configuration of the many
that are possible. Illustrated is the short operating rod, and the
gas cylinder, and in line nature of the system. Also pictured is
the new operating rod guide. The parts are preferably made of
ordnance grade steel but other materials can be used if treated
properly and of suitable strength and wear characteristics. The
parts to be made by any normal method such as milling, casting,
forging or the like.
[0021] FIG. 7 Shows the stock group of the rifle in a standard
rifle configuration with traditional stock, as well as the new hand
guard and a short optics rail at 12 clock position. This part is
made of any suitable material by an appropriate method for a gun
stock. The hand guard is to be made of aluminum, properly treated
or other suitable material for holding the threads required for its
designed attachment to the stock.
[0022] FIG. 8 is the trigger group shown in standard configuration.
The part to be made from steel or other suitable material. The part
houses the internals of a standard M1 rifle trigger housing, plus a
magazine release system, and guide arms to ease entry of the
magazine to the well. The guide arms also serve to help lock the
rifle into the stock, and locate the receiver by aligning with the
magazine well of the receiver. The trigger guard is used to lock
the trigger group to the receiver at the magazine well, and there
by lock the rifle into the stock. The part to be milled, cast,
forged or by other accepted methods. The heat treat of the material
will key to extending its life and giving suitable performance.
[0023] FIG. 9 is the Magazine group, shown made from steel with
internal parts also of steel, this part could also be made of
aluminum, composites, or the other metals. The part to be stamped
and welded or formed by other methods depending on material used.
The part to be available in variations for various calibers and
capacities.
[0024] The end user of the invention will see enhanced reliability,
accuracy, versatility and longer life of this invention compared
with current semi-automatic rifles available. While the listed
configurations of the invention are the preferred embodiment at
this time, those skilled in the art will see that minor changes to
the methods, materials, or design will not depart from the
invention, and therefore it is aimed to cover all such changes
which fall within the spirit and scope of the invention.
