TACOM maintenance advisory
message 05-038 authorizes
the use of British 5.56mm
rounds for training only
with the M16A2/A4 rifle, the
M4/M4A1 carbine and the M249
machine gun.
The British round leaves more
powder residue, which causes
the weapon to jam if it’s not
cleaned frequently.
British ammo is
stamped on its
base with either
L1A2 or L2A2.
if ammo is left lying in the hot
sun, its propellant burns
faster,
which creates
greater pressure
inside your weapon.
Too much pressure
can
damage
your weapon.
if at all possible,
keep ammo
shaded.
if ammo is
hot,
let it cool
before
firing.
I’m sorry, old chap,
but
I’m not supposed
to shoot british rounds
except for training.
quite
so!
I can
leave quite
a mess.
I’m glad they finally
realized how
important
it is to keep you out of
the HOt sun!
zounds!
When you’re
through training,
clean your
weapon and then
re-zero it with
U.S. ammo.
I’m gonna
look
great
when they
get ready
to fire me!
You’re
tOo hot
to fire!
