The
introduction of the Sig 556
at the 2006 SHOT
Show

No
other semi-automatic rifle has captured the imagination
of the shooting public like the SIG 550 series
rifle. For years this legendary Swiss made rifle
has been restricted to law enforcement and military
sales where it has continuously built on its reputation
for outstanding performance, accuracy and durability.
Now, the time has come for a U.S made version.
SIGARMS
introduces the U.S made SIG 556 rifle.The SIG
556 features the same high performance two position
adjustable gas piston operating rod system engineered
our sister company Swiss Arms and marries it to
a trigger housing that not only cuts the rifle’s
weight by a pound but is designed to accept standard
AR magazines.
Originally developed to work under the extreme
situational pressures and environmental conditions
of the Swiss Army on alpine duty, the new SIG
556 delivers when it counts regardless of ammunition
type and variances in gas pressure or case material.
The
SIG 556 features a 16” military grade cold
hammer forged barrel with a twist rate of 1 in
9”. The barrel is locked to the steel receiver
through a unique system that allows the user to
easily change out the barrel. The forearm housing
the gas operating system is a vented non-slip
polymer featuring the SIG TriRail design with
three integrated Picatinny rails for mounting
accessories. There is a forward mount for right
or left side sling attachment The flip-up front
combat sight is adjustable for windage and elevation.
The Picatinny rail equipped receiver is made of
high strength carbon steel with a durable wear-resistant
Nitron X rifle finish. The trigger housing made
from a heat treated aircraft grade aluminum alloy
with a hard coat anodized finish designed to survive
extreme conditions. The rifle comes equipped with
a smooth two-stage trigger.
The
SIG 556 also features an ambidextrous safety and
is designed to accept standard AR magazines. A
rugged 30-round polymer magazine is supplied with
each rifle. Spare battery compartments are provided
in the ergonomically designed pistol gnp as well
as the rubber padded watertight buttstock. The
buttstock also offers two sling attachment points.
In
addition to the standard model SIG 556 which will
begin to ship in late summer 2006, SIGARMS will
also offer a SIG 556 L featuring a longer forearm
but also equipped with the 16” barrel. The
556 L will be ideal for upgrading to the 20”
barrel more precision oriented shooting.
The
third model for 2006 is the SIG 556 SWAT. The
SWAT model will feature same compact design of
the standard SIG 556 with 16” barrel but
will feature a flattop Picatinny railed receiver
and a tactical quad rail.
These
three rifles are the first of several new SIG
556 models that are currently development at SIGARMS
The wait is over. The new U.S. made SIG 556 begins
shipping in late summer - because the time has
come.
