Standardization Edit

STANAG 4179 was agreed in October 1980. The magazine design chosen for this standard was originally designed for the M16 rifle. The decision was predicated on the adoption of 5.56x45mm ammunition (STANAG 4172). Many NATO member nations, but not all, subsequently developed or purchased rifles with the ability to accept this type of magazine.

STANAG 4179 is a dimensional standard and compatible magazines can be made to almost any capacity. Typically, those used for military service hold 20 or 30 rounds of ammunition. Other magazines have included 90RD drum magazines and 100RD Beta C-Mag drum magazines, but these are not standard military issue.

Compatible rilfes Edit

The following military rifles accept STANAG 4179 magazines:

Notes and references Edit

  1. The earlier G1 model only accepts 25RD proprietary magazines.
  2. Requires simple change of modular magazine well.
