Abstract
A magazine for a firearm is provided. The magazine includes a first wall and a second wall coupled to the first wall to define an enclosure. A first projection extends from a first portion of the first wall, a first end of the first projection being adjacent an end of the first wall, the first projection having a first angled surface opposite the first end. A second projection extends from a second portion of the second wall, a second end of the second projection being adjacent the first end, the second projection having a second angled surface arranged opposite the first angled surface.
Claims15
A magazine for a firearm comprising:
- a first wall;
- a second wall coupled to the first wall to define an enclosure to receive ammunition cartridges and an elongated cartridge exit opening comprising a first opening portion, a second opening portion and a transition opening portion;
- a curved first projection extending from a first portion of the first wall and including a first edge substantially parallel to the first wall, a first end of the first projection being adjacent an end of the first wall, the first projection having a first angled surface opposite the first end and having a first angled edge oriented at an acute angle to said first edge;
- a curved second projection extending from a second portion of the second wall and including a second edge substantially parallel to the second wall, a second end of the second projection being adjacent the first end, the second projection having a second angled surface arranged opposite the first angled surface and having a second angled edge oriented at an acute angle to said second edge;
- the first opening portion defined by said first edge and said second edge;
- the second opening portion defined by the first wall and the second wall, the second opening portion being larger than the first opening portion;
- and
- the transition opening portion defined by the first angled edge and the second angled edge, said transition opening gradually transitioning from a narrow gap to a wider gap between the first opening portion and the second opening portion.
5 more elements
A magazine for a firearm comprising:
- a generally parallelepiped container comprising a first wall and a second wall and defining an exit opening comprising a first opening, a second opening and a transition opening at a top portion thereof;
- the first wall defining a first plane and having a first end with a first portion and a second portion, the first portion having a first projection that curves about 90 degrees relative to the first plane, the first projection having a first edge that is substantially parallel to the first wall and a first angled surface having a first angled edge oriented at an acute angle to said first edge and extending between the first edge and the second portion;
- and
- the second wall defining a second plane the second wall having a second end adjacent the first end, the second wall having a third portion adjacent the first portion and a fourth portion adjacent the second portion, the third portion having a second projection that curves about 90 degrees relative to the second plane and towards the first projection, the second projection having a second edge that is substantially parallel to the first edge and a second angled surface having a second angled edge oriented at an acute angle to said second edge and extending between the second edge and the fourth portion, wherein the first portion and the third portion define the first opening, and the second portion and the fourth portion define the second opening, and the transition opening being defined between the first and second angled edges and between the first and second openings, said transition opening gradually transitioning from a narrow gap to a wider gap between the first opening and the second opening.
1 more element
A magazine for a firearm comprising:
- a pair of side walls joined to define an enclosed region sized to receive ammunition cartridges;
- a pair of opposing projections extending from a first end of the pair of side walls, each of the pair of opposing projections curving about 90 degrees toward a center of the magazine, each of the pair of opposing projections having an edge extending from a second end of the pair of side walls, each pair of opposing projections further having an angled surface extending at an acute angle from the edge and away from the center of the magazine, wherein the pair of side walls define an opening having a first portion between the edges and a second portion between the third end and a fourth end opposite the first end, and wherein the angled surfaces define a transition opening which continuously increases in width between the first portion and the second portion.
