STANAG magazine

Many NATO members, but not all, subsequently developed or purchased rifles with the ability to accept this type of magazine.

As a result, in March 2009, the U.S. military began to accept delivery of improved STANAG magazines.

[10] To increase reliability, these magazines incorporate heavier, more corrosion resistant springs and new tan-colored anti-tilt followers.

The magazine uses a blue follower and a tan body which presents the rounds with a better angle to the weapon's feedway, preventing the hardened steel tip of the EPR from contacting the aluminum feed ramp of the M4 carbine, increasing mean rounds between stoppage by 300%.

There are a wide range of both commercial and military type loading tools available for STANAG magazines.
