US 2014/0150322 A1 · Magazine Spring Compression Tool and Method

Abstract

A tool, implement or apparatus and a method of use of the tool, implement or apparatus to aid in the disassembly and assembly of a firearm magazine for cleaning, maintenance or repair when that magazine has a sealed base plate and requires the removal of the spring and spring follower from the top of the magazine. The tool consists of two parts—a body and a pin. The method consists of using the tool body to apply a pushing force or compressing operation directly to the magazine follower and thereby compressing the follower and the magazine spring. The pin is inserted through the magazine box through witness holes to release spring tension from the follower allowing it to be removed. During reassembly, the tool body is used to apply a pushing force or compressing operation directly to the magazine spring compressing it into the magazine box and holding it in place to allow insertion of the pin through the magazine witness holes and to allow insertion of the follower.

Dependent claims

A tool, implement or apparatus for applying a pushing force or performing compressing operations directly to the magazine follower, and simultaneously to the spring of a magazine for semi-automatic or automatic firearms comprising:

a body and a pin constructed of thermoplastic resins (general purpose, engineered plastics, glass and fiber reinforced plastics), metal, alloys, composite materials, or ceramics or other material that has sufficient tensile strength to withstand the force of the spring acting against the tool body or the pin
grooves along either side of the tool body strategically located to allow the body to lock into place when pushed against the lips of the magazine
a shape, including a square, a triangle or rod, that allows the tool to be inserted into the magazine and to depress the follower
a size or dimensions equal to a single caliber cartridge and magazine or
a size or dimensions equal to multiple caliber cartridges and magazines
a pin housed in a cap or otherwise stored in a cavity within the body.

3 more elements

A two piece tool consisting of a body (piece 1) and a retaining pin (piece 2) for disassembly and reassembly of a firearms magazine for cleaning or maintenance, said magazine consisting of a case having a hollow generally rectilinear configuration with two flat parallel side faces, a front face, a rear face and a base end with a non-removable base plate and an open upper end,

the base plate formed in a flat generally rectangular configuration and coupled to the base end to close the base end thereby forming an interior recess within the case,
the upper open end having a wide section equal to the dimensions of the flat edge of the cartridge to be inserted into the magazine,
the upper ends of the side faces having a radial bevel to form a lip on both sides thereby restricting the opening into the recess of the case, said feed lips having a length and a clearance,
a coil spring having an upper end and a lower end positioned on but not attached to the base plate and sized to be slightly longer than height of the interior recess of the case;
a follower positioned within the recess and upon the spring having a central section for positioning the spring and is adapted to smoothly slide up and down within the recess without binding, and
witness holes along the sides of the magazine case that are parallel to one another, and said tool consisting of a body that includes channels on opposite sides of the body, said channels having a width that is less than the clearance between the feed lips and
a second surface width above and below the channels that is greater than the clearance between the feed lips but equal to the dimensions of the flat edge of the cartridge to be inserted into the magazine, and
consisting of a retaining pin which is smaller in diameter than the witness holes in the magazine,
is no longer than the length of a cartridge intended for use in the magazine and,
is inserted into a recess in the tool body for storage said retaining pin being.
