Корпус окончательно утвердил запрет на использование коммерческих пластиковых магазинов. Основная причина, конфликты в подаче у M27 IAR. IAR предназначен для замены M249 и сейчас активно закупается. Хотя ходят упорные слухи, что настоящая цель - замена M4.
Polymer rifle magazines, preferred by many combat troops for their
durability, have been banned by the Marine Corps, according to a new
administrative message published Monday.
only standard-issue 5.56mm metal magazines are approved, according to
the message, signed by Lt. Gen. Richard Mills, the Marine Corps’ deputy
commandant for combat development and integration. They have a 30-round
capacity with either tan, green or black followers, the internal plate
that pushes rounds into a rifle’s chamber.
The message announces a handful of updates stemming from the Corps’
most recent marksmanship symposium, held in October. Marine officials
reviewed everything from approved combat equipment to marksmanship
training and education.
The polymer magazine ban is likely to
upset Marines who tout their superior durability. Traditional metal
magazines do not spring back once they are bent, meaning they may not
feed rounds properly to the weapon — a grave concern in the heat of a
Some manufacturers of polymer magazines claim their
products still function properly after routine bumps and drops, being
rolled over by heavy tactical vehicles and, in some cases, after being
penetrated by a bullet.
Marine officials began ad hoc bans on
polymer magazines last year, citing concerns over their lack of
compatibility with select weapons. The new message from Mills, who
doubles as the commanding general of Marine Corps Combat Development
Command, makes the ban official across the force.
While they work
well in standard M16 and M4 rifles, polymer magazines present potential
problems when used with the Corps’ new M27 Infantry Automatic Rifle,
which is being fielded throughout the force as a substitute for the M249
Squad Automatic Weapon in some formations. More than 5,000 M27s have
been delivered to the Corps, with many in the hands of deploying
Marines. An additional 1,400 are slated for delivery in the months to
The M27 has unique tolerances in its magazine well that can
prevent polymer magazines from seating correctly, resulting in failures.
That poses the risk for malfunction should an automatic rifleman share
magazines with his squad members during a firefight. Metal magazines are
standardized across the Corps’ 5.56mm rifles.
produce polymer magazines are releasing new products they say are
designed fix compatibility issues. This summer, for instance, Magpul
released its third-generation polymer magazine, which it bills as
compatible with the M27. It remains to be seen whether this may sway the
Corps to reverse its ban.
