Adjustable Weight Firearm Buffer
Abstract
This invention is a serviceable buffer for an AR-type rifle such
as the AR-15. This invention satisfies the need for the user to
adjust said buffer weight by opening the buffer housing and adding
or removing internal weights to achieve the desired recoil effect.
In order for the firearm to function properly, buffer weight is a
critical factor in the ejecting of the spent shell casings from the
firing chamber and cycling of the firearm.

Claims
1. An adjustable buffer assembly for a firearm that may include the
following: a hollow housing with an internally threaded opening on
one end; a series of internal weights that are housed inside the
housing; a threaded strike face portion that attaches to the
housing to contain said weights; a roll pin; and a plastic or
rubber bumper.
2. An adjustable buffer assembly for a firearm as described in
claim 1 in which the hollow housing and the threaded strike face
portion are joined together by a threaded interface.
3. An adjustable buffer assembly for a firearm that may include the
following: a hollow housing with an internally threaded opening on
one end; a series of internal weights that are housed inside the
housing; a threaded tail cap that attaches to the housing to
contain said weights; a roll pin; and a plastic or rubber
bumper.
4. An adjustable buffer assembly for a firearm as described in

DETAILED DESCRIPTION OF THE INVENTION
[0007] 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.
[0008] Broadly, an embodiment of the present invention generally
provides a method for changing out the internal weights of a
carbine-type buffer or rifle-type for an AR-type firearm. It is
necessary for the user to optimize the buffer weight for the
purposes of assisting in the ejection of spent shell casings from
the firing chamber and cycling of the firearm.
[0009] FIG. 1 shows an isometric view of the exploded
representation of an embodiment of the invention illustrating the
internal components. The invention may include a buffer housing (1)
with an internal female thread, internal weights (2), buffer cap
(3) with a male thread portion, roll pin (5) and bumper plug (4).
In this embodiment, the bumper plug (4) and buffer cap (3) are
joined together using a roll pin (5) which is intended to be a
permanent mating. The user then selects the necessary internal
weights (2) to achieve the desired recoil effect and inserts said
weights into the internal cavity of the housing (1). The threaded
housing (1) and buffer cap (3) are then joined to one another by
way of a threaded interface which completes the assembly.
[0010] FIG. 2 shows an assembled top view of an exemplary
embodiment of the invention. The invention may include a buffer
housing (1) joined to the buffer cap (3) by way of a threaded
connection, a bumper plug (4) joined to the buffer cap (3) by the
insertion of a roll pin (5). In this embodiment, the bumper plug
(4) and buffer cap (3) are joined together using the roll pin (5)
which is intended to be a permanent mating.
[0011] FIG. 3 shows a cross section view of an embodiment of the
invention showing the internal components. The buffer housing (1)
is shown mated with the buffer cap (3) and the internal weights are
enclosed within the buffer housing (1). The roll pin (5) is
installed into the bumper plug (4) and buffer cap (3) via
concentric radial voids.
[0012] FIG. 4 shows partial cutaway of an embodiment of the
invention installed within the butt stock of an intended AR-type
firearm. This illustration is intended to show the placement of
buffer assembly (6) within the butt stock (8) of the rifle. The
buffer assembly (6) is held in the forward position of the rifle by
the buffer tube (7).
[0013] FIG. 5 shows a close-up cutaway of an embodiment of the
invention installed within the butt stock of an intended AR-type
firearm. This illustration shows the installation of the buffer
assembly (6) within the buffer tube (9) and being supported in the
forward position by way of the buffer spring (7). The buffer tube
(9) is an internal cylindrical cavity within the butt stock (8)
[0014] In an exemplary embodiment, the device may be used with all
types of firearms that utilize an internal buffer mechanism for the
purpose of reducing recoil effects and cycling of the firearm.
[0015] 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 claim.
