GEMTECH IS THE LEADER IN SILENCER
DESIGN, INNOVATION, AND TESTING.
A SUPERGROUP:
Gemini Technologies began in 1993, as a supergroup
of already-leading suppressor designers with roots in
the silencer business going back to 1976. Mixing this
old-school experience with modern CNC and robotic
construction methods, honest business ethics, and a
customer-first attitude, Gemtech has grown year after
year, proving itself over time while other companies
with their “lifetime guarantees” came and went. You will
rarely hear anything other than the highest praise for our
customer service and general lack of internet drama.
We do our job quietly and do it well: Designing, testing,
manufacturing, servicing, and selling the best quality
silencers and accessories at absolutely fair prices.
AROUND THE WORLD:
Gemtech suppressors are in duty use around the
world with many Soldiers, Sailors, Airman, Coast
Guardsmen, and Marines of the United States Military.
Our suppressors are also in use by intelligence agencies,
federal law enforcement, state and local police officers,
wildlife and agricultural agencies, friendly foreign
militaries, foreign police agencies and tens of thousands
of civilian sports shooters. We serve each part of our
diverse client base to the best of our ability, and every
day we come to work to help out people just like you.
WE HAVE BEEN BUILDING SILENCERS
FOR DECADES, AND LOVE WHAT WE DO.

AND MORE
CONSISTENT
“Complaints that a suppressor somehow
degrades accuracy, ballistic efficiency
or precision are pure mythology. While
suppressors do not make your rifle more
accurate, they certainly allow you to shoot it
more accurately. In my 15 years of training
police marksman, this has proven true
hundreds of times. Well-built suppressors
reduce felt recoil, especially on 7.62MM NATO
rifles. They reduce muzzle rise and flash and all
but eliminate the concussive effect felt by the
shooter. Repeat shots are faster, accuracy is
better and marksmen teams remain concealed
after application. The better the suppressor, the
greater the effect…
Gemtech has been building quality suppressors
since 1993. That experience, coupled with the
company’s long-standing focus on customer
service, has put Gemtech at the forefront of
the suppressor industry. Gemtech suppressors
have been deployed by some of the world’s
most elite units, and they are frequently found
attached to the rifles of America’s working law
enforcement professionals.”

G-CORE
®
SILENCERS
The G-Core design began its life as a simple hand
drawing from one of our engineers’ brainstorming
sessions in the summer of 2013. The idea for a solid
two piece design was not something new in the
world of suppressors; however the unique use of
turbulence voids had some merit. We began modeling
this design in computational fluid dynamic software,
which engineers just intuitively know how to use. The
design proved strong and durable in the program, so
to maximize the strength and weight properties, we
used another program called finite element analysis.
It looked even more promising. The engineers had the
shop guys crank out a couple of prototypes and then
we shot them, a lot... probably in ways we weren’t
supposed to. We couldn’t break them. We rejoiced.
After our success we all had a meeting to discuss what
to name this masterpiece of silencing goodness. With
heavy debate we came up with the name G-Core.
USING A COMBINED TOTAL
OF OVER 60 YEARS OF
SUPPRESSOR DESIGN AND
INNOVATION, THE G-CORE
WAS OPTIMIZED FOR SOUND
REDUCTION AND ACCURACY
DESIGNED USING THE
LATEST COMPUTATIONAL
FLUID DYNAMICS (CFD)
SOFTWARE
FINITE ELEMENT ANALYSIS
(FEA) SOFTWARE WAS THEN
USED TO ANALYZE THE
G-CORE TO ENSURE THAT
IT WAS BOTH DURABLE AND

RIGOROUS LIVE-FIRE
TESTING WAS CONDUCTED
FOR EACH MODEL TO
CONFIRM THAT THEY
MEET ALL OF THE WEIGHT,

CUSTOMERS DEMAND

THE SCIENCE OF SUPPRESSION
Sound is air in motion and consists
of pressure variations that the
human ear can detect. It is a form
of overpressure usually measured
in Pascals, and the sound pressure
level humans are exposed to varies
from millionths of a Pascal to billions
of Pascals. Because of the wide
range and unwieldy numbers, sound
levels are expressed as a logarithmic
ratio of the measured pressure to the
threshold of human hearing (defined
as 0 decibels or dB for short).
Firearm sounds are short-duration
pulses produced by a sudden
release of extremely high pressure
gases suddenly exiting a barrel
at the instant of bullet uncorking.
The sound produced varies with
cartridge, powder charge, caliber,
and barrel length from approximately
140 dB (.22 rifle) to over 165 dB
(centerfire rifles). As barrels shorten,
the pressure at uncorking increases
dramatically. Firearm sound levels
over 140 dB will damage hearing.
The purpose of a sound
suppressor (often called a silencer)
is to reduce the high pressures
and sound levels before the gases
have a chance to escape to the
atmosphere. The simplest method
of reducing pressure is to increase
the volume from that of the weapon
bore by attaching a chamber with
a bore sized exit hole to the end
of the barrel. The second method
design is to provide products
that are first hearing safe and
structurally sound and secondly
as compact and lightweight as
consistent with the first priority. To
achieve these goals a myriad of
designs are prototyped and tested.
Sound signatures are recorded with
tools that meet the requirements
of reducing the peak sound is to
momentarily trap gases so they
exit the suppressor chamber over a
greater period of time. The later is
accomplished by a series of baffles.
There is a lot more to designing
a sound suppressor than stuffing
washers into a pipe, or jockeying a
flow simulation program. Knowledge
of design comes from years of trial,
error, and experience. Gemtech
designers each have multiple
decades of design experience.
Gemtech believes that the most
important aspect of suppressor
of MIL-STD-1474D. In addition, all
suppressors have been tested for
structural integrity by measuring
internal peak pressures and
material strengths at elevated
temperatures. Gemtech uses only
the strongest alloys of titanium,
inconel, aluminum, and stainless
steel. Material choice will vary with
the intended caliber, duty cycle,
host weapon, and barrel length.
Then, and only then, are the
designs submitted for production,
and finally laser engraved with the
Gemtech logo and serial number.
Firearm sound levels over
140 dB will damage hearing
DEEP ROOTS IN TESTING:
We have been building and testing silencers for more than twenty years. Don’t
call us old-fashioned, we just believe, in order to trust the numbers being spit out
of the new pressure modeling software, you need to know the reality from real
hands-on testing. We didn’t get into to this business to sit behind a desk, we got
into it to be the best at shooting quietly.

This is an old-school water-test pulled from our 20-year archive. Dip silencer in water, drain, fire 30
rounds of live ammo which heats the silencer to around 800˚, dip in a tub of water and cool, repeat,
repeat, repeat... all day... to see if we can break it.

“I want to drop you all at GEMTECH a
brief note to let you know how much
I appreciate your products. Primarily
I use sound suppressors for hunting
here in Oregon, for everything from
sage rats and coyotes in the Oregon
desert to hunting elk and deer in the
blue mountains. Although the use of a
silencer is not a necessity, using them
on my firearms has vastly improved
my skills as a shooter. I find that I am
a more relaxed, focused shooter while
practicing and when It is time to take
a critical shot in the field. I have also
found that the speed and precision
of subsequent follow up shots (that
are sometimes required on big game)
has improved with the use of sound
suppressors on my large caliber rifles,
allowing me to truly focus on the shot.
I would also like to take this opportunity
to thank you for your excellent customer
support. I must admit when I first
decided that I wanted to purchase a
silencer for hunting with, I did not know
where to start in building up a base
of knowledge to purchase what best
fit MY needs. The staff at GEMTECH
has always been friendly and helpful
in answering any questions that I have
had about your products, and has
always guided me in the right direction
in finding the correct suppressors.
I have enjoyed using GEMTECH
products now for nearly ten years, and
plan on many more to come.“
Thanks again.

Not only useful for covert military operations, subsonic bullets
are great for animal control officers and others who need
a suppressed firearm to avoid alarming the other animals,
nearby livestock, or bothering the neighbors. Subsonic bullets
in legally suppressed firearms are also fun to shoot for target
practice, eliminating the sonic crack.

Gemtech .22LR Subsonic Ammunition:
“For what this new ammunition is designed
for; I love it. It’s quite accurate, and feeds
everything I own that uses a suppressor.
If there is a stand out feature, it has to be
the reliability of the subsonic round. There
are plenty of quiet ammunition options,
but many tend to have problems cycling a
wide range of semi-automatic actions. The
Gemtech ammunition ran smooth and quiet.
Even with the typical velocity devastation in
rimfire ammunition, I did not have a single
round break the sound barrier.”
— Precision Shooting Magazine

“I am a 3-gun competition shooter, and I shoot several rifle
calibers with Gemtech suppressors, as well as .22LR on rifles
and pistols. Shooting .22LR suppressed is great for training
and makes instructing much easier without all the hearing
protection normally needed during a day at the range. I was
amazed by the amount of noise reduction using my Gemtech
with center fire rifle cartridges, but best of all, I was totally
impressed by the reduction in recoil which helped with the
speed and accuracy of follow up shots. I totally recommend
using Gemtech suppressors as a means to improve your
shooting enjoyment for recreational or competitive needs.”
Sincerely,
Robert Johnson
