Ammunition magazine
View Patent ↗The present disclosure provides a method of creating a visible indicator upon a firearm magazine. The method may comprise fabricating a plurality of rectangular matrices of divots on an exterior surface of the magazine, the divots having concave surfaces, each matrix comprising a plurality of rows of divots and a plurality of columns of divots. A first divot of a first row is also a first divot of a first column, the first divot forming a substantially straight line with each other divot of the first column, and a first divot of a second row is also a second divot of the first column. The method may then comprise marking, with paint or ink, at least one of the divots.
1. A method of creating a visible indicator upon a firearm magazine, the method comprising:
fabricating a plurality of rectangular matrices of divots on an exterior surface of the magazine, the divots having concave surfaces, each matrix comprising a plurality of rows of divots and a plurality of columns of divots, wherein,
a first divot of a first row is also a first divot of a first column, the first divot forming a substantially straight line with each other divot of the first column; and
a first divot of a second row is also a second divot of the first column; and
marking, with paint or ink, at least one of the divots.
2. The method of claim 1 , wherein marking, with paint or ink, at least one of the divots, further comprises:
marking a plurality of divots in at least one single column, thereby forming at least one substantially straight line of marked divots.
3. The method of claim 2 , further comprising:
writing a visibly discernable letter or number comprising the at least one substantially straight line of marked divots.
4. The method of claim 3 , further comprising writing a second visibly discernable letter or number on a second of the plurality of matrices.
5. The method of claim 1 , wherein the divots having concave surfaces are fabricated by chamfering.
6. The method of claim 1 , wherein the exterior surface of the magazine is fabricated out of a polymer, and further comprising:
purposely erasing the paint or ink from at least one of the divots.
7. The method of claim 6 , further comprising:
re-marking at least one of the divots that has been purposely erased.
8. The method of claim 1 , wherein each of the plurality of rectangular matrices comprises exactly three columns and five rows of divots.
9. The method of claim 1 , wherein marking further comprises filling a plurality of divots in succession within a row or a column, and then in succession in a next row or column, in order to indicate a numerical tally.
