Earlier today, at 191737Z, the USMC issued a message entitled, “M4/M16 SERIES/M27 MAGAZINE GUIDANCE UPDATE”, directing which magazines will be used by Marines with the M4/M16, M27 and M249.
In addition to the Army’s new Enhanced Performance Magazines (NSN 1005-01- 630-9508) which will replace the legacy magazine in the stock system, PM Individual Weapon Systems also authorizes the GEN M3 PMAG in Black (NSN 1005-01-615-5169) and the new Medium Coyote Tan (NSN 1005-01-659-7086). Of note, the Army’s EPM is authorized for training use only!
This is huge news for Magpul because this is the first service-wide adoption of their magazine. Not only that, it’s the only magazine authorized for use in combat.
Here is the meat of the message:
