With the purchase of this SUREFIRE flashlight,
you have invested in one of the world’s best
“illumination tools.”

We believe it to be a prime example of our
philosophy that design decisions should always
be made in the interest of the product being the
very best it can be.

Frequently, this means deciding to use a
more costly process or a more expensive
material than would normally be called for. We
have, however, learned that in order to produce
the best, one must do it right.

We thank you for supporting this decision
and electing to confirm our belief in “no
compromise” in a product that, by its
performance and reliability, may some day be
called upon to save your life.

There is no other choice.

WELCOME

TO THE SUREFIRE TEAM



SUREFIRE lights provide overwhelming

power, and they do this with a quality of
beam that is unmatched in brilliance and
performance.



SUREFIRE’s high pressure Xenon/
Halogen lamps operate at the highest
temperatures possible, producing
extraordinary, brilliant, white light.



Our reflectors are machined from solid
billets of aircraft grade aluminum.



Each SUREFIRE lamp assembly is
permanently prefocused to within less than
five thousands of an inch to achieve the
absolutely flawless SUREFIRE beam.



The switch is ergonomically located for in­the-dark positive activation.



Whether you need a small light that can
be carried in your pocket or a multipurpose
professional light, SUREFIRE offers you
models that range in power from 15
lumens to 500 lumens.



You can have confidence that your choice
of a SUREFIRE light will always reward
you with years of superb, unfailing
performance.

You have just become the owner of one of the
most incredible pieces of lighting technology
ever conceived. It is a masterpiece of
engineering, a member of the SUREFIRE
family which has gained the acceptance and
respect of military and law enforcement
professionals around the world.

The M4 Devastator can drive an intense,
concentrated light beam deep into the night,
revealing objects at over 100 yards.
The M4 Devastator utilizes the exclusive
SureFire beam that combines a brilliant
prefocused spotlight center with a
surrounding flawless, uniform, wide,
floodlight that is free of irregularities and dark
spots. This enables you to shine the spot on
the subject of primary interest and at the same
time illuminate a wide surrounding area so
you maintain peripheral awareness.
To give you maximum control of the
light, the M4 utilizes a proven fail-proof
switch system introduced by SureFire. For
quick access and momentary light, a pressure
switch located on the tail cap is easily located
by feel, regardless of the position of the
flashlight in your hand. When constant light
is needed simply rotate the tail cap clockwise;
you can deactivate the light to prevent
unintended activation during covert
operations.
For greater reliability, the M4 lamp
assembly is protected against shock from
impacts.

Along with all of these benefits, the
weather resistant design, Mil. Spec. finish and
aircraft grade aluminum construction makes
the M4 the unquestionable best choice for
numerous marine, urban, and rural
applications.
