SAVAGE ACCUTRIGGER REVIEW
Innovative, Remarkable, Reliable. . .Getting Inside
Savage's Accutrigger
By Dick Metcalf
Savage Arms has
long been known for manufacturing extremely accurate,
extremely reliable, and extremely economical bolt-action
centerfire rifles. Now it has introduced a revolutionary
trigger design that will forever change the way shooters
expect triggers to function on store-bought guns. The new
Savage AccuTriggerTM is absolutely crisp and creep-free. It
is easily user-adjustable from 6.0 to 1.5 pounds. And it is
absolutely safe. It won't fire if dropped or bumped at the
lightest setting or even if you throw it from the top of a
20-foot forklift down onto a concrete floor--which is
exactly what Savage Arms owner and CEO Ron Coburn did in the
factory to prove to himself it worked when his engineering
team showed him their finished prototype.
Think about all that for a minute: An ordinary,
production-grade rifle with a trigger that breaks
competition-grade crisp and clean at only 1.5 pounds and
priced at Savage's traditional moderate level.
The AccuTrigger project got started several years ago
when Coburn decided he wanted Savage rifles to have the same
reputation for out-of-the-box trigger precision as they
already had for out-of-the-box accuracy. A lifelong serious
hunter, Coburn was as frustrated as every other rifle
shooter in the world by the liability constraints that
inhibit the availability of top-quality, adjustable trigger
mechanisms on regular-production hunting rifles. Most
factory-production firearms triggers today have very heavy
pulls. No secret why: No manufacturer can afford the legal
risk of producing firearms with light or adjustable triggers
that might accidentally discharge. Of course, some factory
rifle triggers do have screws to adjust sear engagement
pressure or trigger travel/overtravel; on others a gunsmith
can polish component interfaces to reduce sear engagement or
smooth the creep. However, unskilled adjustments to a
factory trigger can create an unsafe condition and will
usually void the factory warranty, and many riflemakers who
sell rifles with triggers that are mechanically capable of
adjustment factory-seal all the adjustment mechanisms with
glue or epoxy so that any tampering is irrevocably evident.
To Coburn that was unsatisfactory. He called Savage
design and industrial engineers Scott Warburton and Bob
Gancarz into his office and gave them a simple mission:
design a perfectly crisp, creep-free trigger for Savage
rifles. Sometime later they came back and showed him a new
mechanism. He tried it and smiled. "That's really good," he
said. "Now make it user-adjustable, from six pounds down to
a pound and a half." They looked at each other and headed
back to their workshop, thinking: "Wish he'd mentioned that
before." A few more months went by, and they were back with
a perfectly crisp, creep-free trigger mechanism that was
fully adjustable with a single screw. "That's really good,"
Coburn said. "Now go make it so it's absolutely safe and
won't jar off no matter what." This time they left his
office thinking: "Really, really wish he'd mentioned that
before." For the next several months the project kept
Warburton and Gancarz awake at night and spoiled their
concentration while bass-fishing or watching football on
weekends. But they finally came back with a mechanism unlike
anything ever done in a rifle before and put it in Coburn's
hand. He worked it, felt it, smiled once again, and then
threw it off the top of a 20-foot-high forklift with the
manual safety off. It didn't fire! Coburn shook hands with
his engineers and said, "If I'd told you at the outset
everything I wanted, you'd have thought I was crazy."
Now the AccuTrigger is in production, and it's an
interesting historical note that the two guys who invented
what is perhaps the most innovative rifle trigger action in
history came to Savage from previous jobs in the revolver
engineering departments of Colt and Smith & Wesson. Reminds
me of the days in the 19th century when men like Horace
Smith, Daniel Wesson, Oliver Winchester, and Eli Whitney all
knew and worked with and for each other at various times.
The great tradition of American arms making continues.
When at rest (#1), the top extension of the
AccuTrigger's AccuRelease lever is positioned
behind the sear. Should anything cause the sear
to jar off (#2), the AccuRelease lever blocks
the sear and prevents firing.

HOW THE ACCUTRIGGER WORKS
To understand the innovative simplicity of the AccuTrigger
and how it operates, look closely at the accompanying
sequence of photographs and illustrations. First you'll
notice that the trigger and the sear levers are notably
longer than those found on conventional trigger mechanisms
with their engagement point out on their ends. This allows
for more leverage (technical term: longer force-moment arms)
than with shorter parts with less tension required for
reliable, crisp engagement. (Think about a seesaw; a long
lever is easier to operate.) With the sear engaging a simple
sharp, shallow notch in the extreme end of the trigger, only
a miniscule trigger movement is required for an instant,
sharp, clean release.
The next essential element is the long silver-colored
AccuRelease lever mounted within the trigger body and
sharing the trigger's pivot point in the housing. When at
rest, the forward upper end of the AccuRelease is positioned
directly behind the sear, where it will block the sear
should any external force cause it to jar out of the trigger
notch. In normal operation, the trigger finger will first
take up and depress the AccuRelease lever so that its
forward tip drops out of the path of the sear, allowing the
sear to move fully backward when released by the trigger at
whatever weight you have adjusted the trigger pull to be.
In normal operation, the trigger finger
completely depresses the AccuRelease lever (#3),
allowing the sear to move completely to the rear
(#4) to fire the rifle.

Several shooters who have seen AccuTrigger-equipped
rifles only from the outside have commented that the system
reminds them of a Glock pistol's "Safe-Action." And in broad
conceptual terms there is indeed a similarity as both
systems involve a trigger-housed lever that prevents firing
until it is depressed as the trigger is squeezed. But the
actual design and mechanical operating principles are
utterly different.
To adjust the AccuTrigger pull weight, simply remove the
two pillar-bedding stock screws, lift off the stock, and
insert the tool supplied with the rifle into the bottom of
the trigger return spring, engaging the spring-tail with the
slot on the tool. For a heavier pull, turn the tool
clockwise. Maximum trigger pull (nominally six pounds) comes
when the spring "clicks" when rotated. For a lighter pull,
turn the tool counter-clockwise. Minimum pull (nominally 1.5
pounds) is at the point when the large coil contacts the top
surface of the trigger and you detect resistance. If you try
to force the spring beyond these limits, you won't create
any danger, but you'll destroy the spring and the pull will
feel lousy.
Incidentally, as part of the AccuTrigger project, Savage
also redesigned the manual safety mechanism for its
bolt-action rifles; the newly designed ambidextrous teardrop
safety on the center rear of the receiver provides much
better acquisition of the safety button and operates much
more smoothly and quietly than the previous design. It is a
three-position safety, which locks both the trigger/sear
interface and the bolt in the full-rear position, locks the
trigger/sear but allows the bolt to be operated for
unloading while in the center position, and is in firing
mode when all the way forward.

comparison of the AccuTrigger trigger pull
profile and other gunmakers' trigger pull
profiles.

While developing the AccuTrigger, Savage employed Dvorak
Instrument's sophisticated TriggerScan analysis computer
software to observe the operation of the mechanism and to
compare objective measurements of the new system with
triggers of other makes and models of rifles. According to
Savage's published results (shown in the accompanying
graphics provided by Savage), these comparisons confirmed
that there is a graphic and repeatable difference between
the AccuTrigger and all other triggers tested. The new
Savage system demonstrates a lighter trigger pull than all
the other major brands (including top-of-the-line imported
brands and custom aftermarket triggers). The AccuTrigger was
much smoother and crisper and broke cleaner with less creep
than any other factory-built trigger tested.
I have used the same computerized trigger/action
TriggerScan instrumentation and software for several years
and independently repeated the same testing procedure as
described by Savage. My results verify all of Savage's
claims and, if anything, indicate Savage is being
conservative. In the accompanying graphic from my analysis,
overlaid tracings of the trigger operation of a Savage Model
12BVSS-S .22-250 both at the maximum setting and the minimum
setting are not only equally sharp and creep-free, they are
exactly co-terminous up to the point of break. In other
words, when adjusting from six pounds to 1.5 pounds, there
was absolutely no measurable change in the trigger position,
travel, pull, or feel--except for much lighter weight. It's
truly a remarkable engineering achievement.

Coburn notes, "Sooner or later, everyone that inspects
the AccuTrigger asks how I ever got our corporate attorney's
blessing. The truth is, I didn't bother to ask. The
AccuTrigger is what shooters have been asking for--an
infinitely adjustable trigger that will suit their own
personal taste while still being completely safe."
COMES AS STANDARD EQUIPMENT
For 2003 the new AccuTrigger is standard equipment on all
Savage centerfire bolt-action Varmint models, Law
Enforcement models, and heavy-barrel long-range rifles,
including Savage's "Package Series" versions of those models
pre-equipped with high-quality Leupold and Burris variable
scopes. AccuTrigger models replace previous models, which
are no longer cataloged. I emphasize that the AccuTrigger is
a standard factory-issue item not a custom or aftermarket
accessory, and it will also be incorporated into various
models in Savage's conventional hunting rifle lines as
quickly as production allows--perhaps as early as this
autumn. The company is certainly not being slow about it.
The production schedule calls for 3500 AccuTrigger units a
month beginning last January 1st.
Okay, an obvious question: How much does the new
AccuTrigger add to a Savage rifle's cost? Savage says about
$35. For example, the manufacturer's suggested retail price
in 2002 for a pre-AccuTrigger, top-of-the-line
stainless-steel, fluted barrel, laminated-stock Savage Model
12BVSS varmint rifle was $616. The same model in 2003, with
AccuTrigger, is priced at $675. That's $59 more, but the
other $24 part of the difference is normal annual price
increase. That's a real bargain compared to any other
maker's standard-production rifle prices, especially
considering that the cost of a custom-match-adjustable
aftermarket trigger for a Savage rifle (or any rifle), plus
precision gunsmith installation, would run several hundred
additional dollars.

And to answer the second question that leaps into a
previous Savage owner's mind when he first tries the feel of
an AccuTrigger-equipped gun--no. The AccuTrigger is not
retrofittable. The rear and bottom areas of the receiver are
milled somewhat differently for the AccuTrigger module and
its accompanying new manual safety mechanism than for the
previous Savage trigger and safety mechanism. So you won't
be able to buy an aftermarket AccuTrigger package and
install it on the Savage rifle you already own.
Having said this, however, I will also report that I
recently spent a day at the Savage factory--where, under the
expert guidance of the Savage engineering and production
staff, I hand-built and assembled a .22-250 Model 12BVSS-S
stainless/laminated AccuTrigger Varmint model. I closely
observed the differences between the AccuTrigger receiver
millings and the standard Savage receiver design, and it is
my (admittedly nonmachinist's) opinion that a professionally
equipped gunsmith/machinist's shop could in fact reconfigure
an existing Savage receiver to install an AccuTrigger
mechanism. But that'll happen only if Savage decides to sell
the triggers to gunsmiths (which is doubtful at this point)
and then only if the gunsmith's customer was willing to pay
nearly as much as the price of a brand-new AccuTrigger gun
just to put the new trigger on an old rifle.
I've been shooting and working with the AccuTrigger since
the spring of 2002 when Coburn first sent me the
heavy-barrel Model 10FP-LE1 Law-Enforcement model in .308
shown in the accompanying photograph with a prototype
trigger mechanism. Equipped with one of Springfield Inc.'s
big tactical scopes, it shoots one-hole groups at 100 yards
with factory ammunition, and the absolutely crisp
minimum-setting trigger will make it a must-have for law
enforcement special operations teams who must make
hair-splitting instant-takeup shots with lives at stake. My
new Model 12BVSS-S .22-250 Varmint prints 5/8-inch groups at
200 meters with factory ammunition, and the precision
trigger is the answer to a predator-hunter's prayer for
long-distance shots at varmints.
The mechanism's trigger pull weight can be
easily adjusted from six to 1.5 pounds by
removing the stock and tightening or loosening
the trigger return spring (L). The AccuTrigger's
built-in AccuRelease lever (R) ensures complete
safety at even the lightest pull weight.

My only problem with the whole thing is--now I'm spoiled.
I want an AccuTrigger on every rifle I own. |
