Hi
Thank you for your inquiry. Below is the information
regarding tuning and costs. Turn around time is usually
between three and four days usually, sometimes sooner. I
hope this will be of help in your decision making
process and that I can be of service to you. If I can be
of further assistance and for shipping information,
please feel free to contact me.

Again, thank you for your considerations and I would
like to be of service to you.
Thank you:

Why a springer airgun tune?
By Charlie
What a tune does, why it's important, whether I do it or
someone else does it.
First: I have yet to see any lower end to mid range
rifles, and others using synthetic seals not having at
least some damage, often times minor, and some with
severe damage, which the buyer will never know even
while shooting it unless it is extremely bad or he
breaks a spring or he has a Chrony and can see the power
loss. Secondly: the vibration or spring twang and
twisting caused by poor or incorrect lubrication, poor
quality control, rough components, and poor spring
design and construction causes’ inconsistency, loss of
power and inaccuracy. Thirdly: either little or no
lubrication or incorrect lubrication of other critical
internal parts. Fourth: smoother, softer, and depending
on the gun, shorter more predictable trigger pull, and
finally, resolves most rough cocking conditions.
Spring twang and/or vibration and cocking roughness.
First there is the rough metal on the interior caused by
poor machine stamping. Two dynamic things that happen
when you pull the springer trigger. First there is
double recoil. When the seer releases the spring, the
gun starts to recoil to the rear. Then when the piston
hits the bottom of the cylinder, it drives the gun
forward. The second thing is that as the gun is cocked,
the spring expands and at the same time twists slowly
until the piston is latched by the seer. It may also
cant or bend the spring during this process. When fired,
the reverse happens, but in a fraction of a second. The
twisting during decompression causes the rifle to twist
in the opposite direction of the twist of the spring.
For every action, there is an opposite reaction of
course. A tune helps reduce much of this violent
reaction.
Tuning, if done correctly and depending on what kind of
tune, reduces spring vibration or twang, often increases
power, smoother cocking operation, softer more
predictable trigger pull if a trigger tune is done, far
less recoil, less torque, more consistent, and more
accurate shot after shot requiring very little service
(lubing and maintenance) for the life of the gun. Keep
in mind though, springs do break on occasion and seals
do go bad and are considered a wear and tear item. I use
nothing but the best seals and springs available for the
particular gun. The best 30.00 for basic parts you'll
ever spend on a springer. If special kits are used, such
as a GSI kit, the cost is considerably more.
About the proper internal lubrication.
Proper lubing is of the utmost importance. How it is
lubed, at what points it is lubed and what lube is used
on those points makes a tremendous difference how your
gun behaves, its accuracy, it’s consistency, seal and
spring life, and it’s longevity. It’s important to know
that there are several lubes that should be used in
airguns for different purposes in different locations
and they all play different roles.
So....many things are resolved by a good tune and these
principles apply to all airguns. You just can't beat the
money spent for a tune, especially if it's tuned
properly.
But please keep in mind, no two guns are the same coming
off the line, or tuned by the same tuner, have the same
power and consistency. Secondly, power should not be the
primary concern, although important. If it's tuned and
comes out extra strong, that’s fine as long as it fires
smooth and is consistent. If not, it should be
“de-tuned” a little.
I believe the Gamo’s and RWS’s are an excellent choice
on the market and I further firmly believe that for the
money they are the best gun to buy for the dollar spent.
Best bang for the buck.
The real value though is that you can SuperTune or
TurboTune them and wind up with a gun that will shoot as
well as some $400-$500 or more dollar guns, for about
half of the cost. They don't all turn out to be
monsters, but most turn out real well.

All Gamo’s including 220-440-880-1000-Shadow Series-CFX
and the 2007 models
RWS 34/36 45/54 RWS 320 RWS-94 and most other guns that
I service.
Usually springs and seals are the only parts required
that I have to purchase, and the spring cost can vary a
little. A Maccari Custom springs and an Apex seal
usually run approximately 30.00. I use Maccari springs,
seals and lubes exclusively where/when applicable and
available. Most other parts are made here in the shop.
Testing Procedure
All guns are Chronied using a twelve shot string before
and after it is worked on. The highest and the lowest
number in the string are deleted and the computations
are based on the remaining ten. Tests are conducted
using the same brand, style, and weight pellets during
the before and after test.
The customer receives a test printout and graph that
includes: (pre-tune) before service and (post-tune)
after service providing the following plus trigger pull
stats:
A- Highest velocity B- Lowest velocity
C- Average velocity D- Extreme spread
E- Average deviation F- Foot pounds energy
Note: New guns may only have one in the service
printout.

TurboTune
For those who want the ultimate
Add $30.00 to the SuperTune ($149.00)
With the TurboTune, in addition to all of the services
performed in the SuperTune I add the PowerGlide TT Kit.
I machine the spring guides from scratch, fitted to your
particular gun and main spring, as well as the spring
seat and guide seat to the trigger block and where
applicable can machine tophats and spring spacers. I can
do that because I have your gun in front of me for
measurements and that of course can't be done with shelf
parts. This provides an even better overall operation of
the gun reducing vibration and shock even more as well
as being more consistent, longer spring life with
virtually no spring vibration or twang, almost
guaranteeing no spring cant, and more even and smoother
cocking. All of this greatly improves the firing cycle.
Depending on the type of piston, on some guns I also use
stainless steel lower spring seats to help reduce spring
torque reaction that causes the gun to rotate when
fired. All of these additional improvements add more
consistency and accuracy. It’s an inexpensive worthwhile
investment in your gun that will last for years and
years.
No matter which level of tune you select, when it's
finished, it's a much improved gun. It’s just the higher
the level, the greater the improvement.
For the Gamo owners, and any others that have a gun
utilizing the Theoben type trigger, you know that the
trigger leaves a lot to be desired. The GRT-III is
available and sold world wide. The cost is $30.00 with
no additional labor charge. It makes a tremendous
difference in the trigger pull, bringing it down from
about 5-6 pounds to about 1 pound 8 ounces and that
along with the ergonomics greatly improving both
accuracy and consistency. Click on this link for
additional information and what it is, and the guns the
GRT-III trigger will work in.
