CS
AR15 "NM" Trigger Return Spring
Set
One of the biggest
complaints we've heard from Service Rifle
shooters is the difficulty of attaining
the trigger characteristics the better
shooters desire and still have a workable,
reliable, and consistent
trigger.
Superior Shooting
Systems Inc. just went a long way towards
attaining that goal. Our chrome silicon CS
NM Trigger Return Springs Set installs on
your two-stage AR15 trigger without any
modifications to the trigger (engagement
adjustment will probably be necessary) and
allows attaining a very light second-stage
break weight while maintaining the tension
necessary for safety and legality in
competition.
The NRA Service
Rifle rules, as well as CMP guidelines,
restrict minimum trigger pull weight to
4-1/2 pounds.
When you shoot a
two-stage trigger, it's the combination of
the first and second stages that
determines its overall weight. For
instance, if there are 2 pounds in the
first stage and 2 in the second, that is a
4 pound trigger. Consequently, maximizing
first-stage weight lets the second be
lighter, and a lighter second stage is
what the shooter feels as the break
weight. A lighter trigger makes trigger
control much more efficient, and results
in much improved shot timing.
Due to adjustment
limitations set forth by its design, the
"trick" to getting a heavier first-stage
weight has been bending the trigger return
spring legs downward to increase their
tension. This works -- for a time. One
problem with making this modification is
that the music wire springs in these
triggers will change radically with use,
and over time. This means that your 4-1/2
pound trigger will NOT always be a 4-1/2
pound trigger. (Even if the rifle isn't
fired, these springs won't last a year
without changing weight.) Changed trigger
characteristics lead to inconsistent
trigger behavior, and, at the worst,
disqualification from
competition.
The Superior
Shooting Systems Inc. CS AR15 Trigger
Return Spring allows the leg bending
modification (and responds better to it
than conventional music wire springs due
to the superior structure and life of
chrome silicon) but many people are not
able to attain desired adequate spring
tension through this
modification.
The solution is to
install TWO SSS Inc. CS AR15 Trigger
Return Springs following the instructions
enclosed. Since the SSS Inc. CS springs
are already lighter in function than the
standard spring, doubling our CS springs
-- with no other modifications made to
them -- normally results in a suitable
trigger. A simple modification (bending
the spring legs, which, again, will not
accelerate spring degradation in CS as it
can with music wire) can increase
first-stage weight to 4 pounds. That
leaves the shooter holding only a half
pound of trigger for the second stage
(assuming the trigger is otherwise
correctly adjusted via manufacturer's
instructions).
The SSS Inc.
solution is one you can count on. Chrome
silicon springs are far more consistent
and stable than standard springs. Our
exclusive use of certified materials and
comprehensive post-winding processes (shot
peening, heat treating, etc.) ensure
perfect spring performance consistency for
the life of the rifle. When the trigger is
functioning at its optimum possible level,
and the shooter knows it will not change,
he can focus on shooting better scores --
and will!
The CS Hammer Spring
is specially engineered to provide faster
rebound (quicker lock-time) than the
conventional spring but at a lower
compression weight (achieved by the
properties of chrome silicon). This allows
improved firing mechanism performance and
a lighter second stage trigger pull.
