Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of priority of U.S.
provisional application No. 62/355,678, filed 28 Jun. 2016, the
contents of which are herein incorporated by reference.
BACKGROUND OF THE INVENTION
[0002] The present invention relates to firearms and, more
particularly, to a pistol caliber blowback operated bolt carrier
group providing an integrated gas key.
[0003] The bolt carrier group is responsible for chambering,
firing, and extracting ammunition cartridges from the host firearm.
The energy to perform these functions is provided by hot gas
channeled through the gas key and into the bolt carrier. For
gas-operated firearms a secure connection between the gas key and
the bolt carrier is required.
[0004] Blow back pistol caliber bolt carrier groups, however, are
notorious for having failures at the fasteners holding the charging
boss or the gas key in place. Mechanical fasteners on bolt carrier
groups are insufficient, and as a result, can result in
catastrophic failures. The fasteners either break or back out over
time. The current devices use an inefficient method of attachment.
The fasteners do not offer enough support to the gas key to be
considered a stable means of attachment and can eventually break,
shear, or back out. Upon such failure, the only way to fix the
problem was to repair or replace the fasteners or charging
boss.
[0005] As can be seen, there is a need for a pistol caliber
blowback operated bolt carrier group providing an integrated gas
key, thereby eliminating the fasteners by integrating the charging
boss into the blow back pistol caliber bolt carrier group.
Eliminating the fasteners required to hold the charging boss and/or
gas key in place eliminates the failure point altogether by
removing the fasteners that cause failure, whereby the present
invention performs the intended role without risk of possibly
dangerous failures.
SUMMARY OF THE INVENTION
[0006] In one aspect of the present invention, pistol caliber
blowback operated bolt carrier group includes a bolt carrier having
elongated generally cylindrical body; and or a charging boss and a
gas key integrally formed into a top portion of said body.
[0007] These and other features, aspects and advantages of the
present invention will become better understood with reference to
the following drawings, description and claims.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] FIG. 1 is a perspective view of an exemplary embodiment of
the present invention;
[0009] FIG. 2 is an exploded view of an exemplary embodiment of the
present invention demonstrated with associated components;
[0010] FIG. 3 is a section view of an exemplary embodiment of the
present invention, taken along line 3-3 of FIG. 1;
[0011] FIG. 4 is a perspective view of an exemplary embodiment of
the present invention; and
[0012] FIG. 5 is a perspective view of an exemplary embodiment of
the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0013] The following detailed description is of the best currently
contemplated modes of carrying out exemplary embodiments of the
invention. The description is not to be taken in a limiting sense,
but is made merely for the purpose of illustrating the general
principles of the invention, since the scope of the invention is
best defined by the appended claims.
[0014] Broadly, an embodiment of the present invention provides a
pistol caliber blowback operated bolt carrier group providing an
integrated gas key. The carrier group providing a bolt carrier
having elongated generally cylindrical body; and a gas key
integrally formed into a top portion of said body
[0015] Referring to FIGS. 1 through 5, the present invention may
include a bolt carrier 10 and associated components made of metal
alloy or other sufficient hard composite material. The associated
components include a weight 12, a weight retaining pin 14, and a
spring 18-loaded firing pin 16 slidably mounted within the bolt
carrier 10.
[0016] The bolt carrier 10 is generally cylindrical in shape with a
longitudinally extending circular bore throughout its length,
wherein elongated openings communicate from a top and bottom
portions of the carrier 10, allowing the hammer to extend into the
interior of the bolt carrier 10 and strike the firing pin 16. The
bolt carrier 10 may extend from a rear portion 30 to a forward
portion. The upper surface of the bolt carrier 10 top of the bolt
carrier is formed with an integral gas key 50. The integral gas key
50 includes a flat charging boss 20 for engagement with a charging
handle. In the circular bore located near the charging boss 20 may
be an extractor 22 having a gripping element to grab and hold onto
a portion of an ammunition cartridge. the extractor 22 may engage
an extractor pin 24 received therein. The weight 12 may be retained
within the bore so as to be flush or just inward with the rear
portion. The weight may be retained by the weight retaining pin 14.
The bore may be approximately 0.250'' in diameter.
[0017] The complete assembly of the above-mentioned components is
referred to as a bolt carrier group. The bolt carrier 10 may be
multi axis machined, machined in several steps or setups, forged,
or cast into the required shape keeping the gas key integrated into
the overall shape.
[0018] A method of using the present invention may include the
following. The bolt carrier group disclosed above may be provided.
A user may use the bolt carrier group without the weight 12 and
associated weight retaining pin 14. The blow back pistol caliber
bolt carrier group, once assembled, can be easily replaced into
existing pistol caliber rifle platforms, i.e. the AR-9, AR-40,
AR-45 family of weapons and their derivatives.
[0019] It should be understood, of course, that the foregoing
relates to exemplary embodiments of the invention and that
modifications may be made without departing from the spirit and
scope of the invention as set forth in the following claims.
