David sent this nice note re: his testing
of the TKO Mod on his Crosman 1701P Pistol....
I have a decibel meter I use with my work. Before at 6 feet,
facing the muzzle the decibels were 85 DB
After installing and testing, accuracy was exactly the same.
However the new sound test revealed 74 DB!
Now I know what a mouse fart really sounds like!
Great product! Easy install, great instructions. Can't say
enough and it exceeds my expectations.

moderator comparison test by a customer:
I was never able to find a comparison on the two moderators
available, the TKO and Wolf Airguns, but today I was able
to compare them side-by-side. (drum roll please.....)
The Wolf Airguns moderators are massive and look like a real
firearm moderator. They are all metal (aluminum outside, not
sure what kind of metal the baffles are). They are huge. 8.5"
long and 1 1/8" diameter and 5 oz in weight. And it's
VERY quiet. I've been using it for about a month and have
tried it both on CO2 rifles and pneumatic rifles. It was impressive.
But my new TKO arrived today. It is 6 5/8" long, 3/4"
diameter, and 1.6 oz. I looked at that tiny thing and my first
thought was, "I wonder what his return policy is, because
there's no way this can silence my gun like the Wolf."
Well, I was wrong. I took it right outside with my high-precision
sound meter (guaranteed to be accurate within 1.5 db) and
tried them out. Here are the results. The first number is
measured at the muzzle. The number in (parentheses) is at
my ear (what you actually hear).
Crosman 2240 with 14" barrel.
No moderator: 105.5-108.6 db (95.9-97.1 db)
Wolf: 99.6 db (86 db)
TKO: 98.3 db (83.7 db)
And yes, you can tell the difference without a sound meter.
The TKO is going on my new Disco which will be coming from
my wife for Xmas. I'll do another comparison and report with
both of them on the Disco when I get it.

word about Airgun Forums...
visit many of the airgun forums to take the pulse of the airgun
hobby. I find that these forums are the best for DIY information
for the airgun hobbiest.
www.gatewaytoairguns.org (I visit the PCP "Gate" most often)
Owners Forum (The "Green Forum" .. A great site
for Crosman specific guns and DIY info.)
Airguns.net (They have a great free classifieds section for lots of airguns
and parts ... careful, if the deal seems too good, it could
be a scam.
TalonAirgun.com (Great info regarding the Air Force brand of guns, as well
as many other airgun subjects.
TedsHoldover.com (Ted is an interesting guy, lots of great review and hunting
videos, and he recently launched a new forum.)

T made a batch of Marauder Pistol tube stocks...
Billy is waiting for his deployment orders (we hope it's someplace
dangerous... like Kansas or Iowa!), he has been helping me
in the shop, making some of his full shrouds for the Hammerli
850 and a half-dozen BT Tube Stocks for the Crosman 1377/1389/1322
and the Marauder Pistols.
The tube stocks are $75 shipped to USA addresses. Use SECTION
7 to order. Enter "BT Tube Stock" in the
Benefits over the Crosman plastic stock:
-- Very fast attachment and detachment (7 seconds timed)
-- Puts the eye about at the perfect height for scope and
-- Very lightweight
-- Allows you to use custom wood grips

A TKO Half-Shroud for the Umarex Fusion Co2 rifle (AKA XS60)
TKO "Half-Shroud" built for the Umarex Fuision Co2
rifle. A nice rifle with a great barrel. The factory brake
is destroyed to remove for fitting of the half-shroud. Very
quiet and looks much better than the large pickle from the
factory. The fill caps usually have sealing trouble, and a
replacement is available from Archer Airguns. This air rifle
also looks like a good candidate for a bulk-fill conversion.

Here is a nice write-up of a Lonestar tuneup I did for a local
fellow a while back:
received a brand new 25cal Lonestar a few weeks back, but
was not very impressed with its anaemic performance. With
a 3300 psi fill, using 25.4gr JSB's, velocity started out
at 820 fps and steadily dropped to 700 fps after 20 shots.Adjusting
the hammer tension did not help much, if any.
I called Mike T (TKO/22) and asked if he'd look at it, not
only to try and juice her up, but to make her a little quieter
too. Mike told me to drop the LS off and he'd see what he
An extremely short time later, I had the gun back home, sporting
a large 1.0" OD shroud, full tune and depinger and a whole
lot more power...OAL is now 4.75 inches longer at 46.75" and
a lot quieter too. You're AWESOME Mike!!!
While the snowy, blizzard conditions here in Omaha Nebraska
have prevented me from shooting her outside, and will probably
continue to do so for the next few days, I have done a little
testing over the ol' chrony and here are the numbers:
Start fill: 2800 psi
1. 980 fps
2. 986 fps
3. 983 fps
4. 989 fps
5. 996 fps
6. 1000 fps
7. 1008 fps
8. 1016 fps
9. 1015 fps
14 974 fps
End fill: 1700 psi
Average velocity: 995fps
Ave energy (25.4gr): 56 fpe

The AAs200/CZs200 air rifle is a great little target gun and
can be made very quiet with the TKO Stage-VMod made specially
The TKO brake can be fitted so that the airtube can be removed
for filling without removing the brake, even with the longer

little project I started a week ago: make one change to a
Discovery valve ... turn down the head to see if there were
performance gains without porting, spring tuning, etc. The
latest Discovery valves have a harder material molded onto
the valve stem. The previous material was soft (Nylon composition)
and not easily machined. This new material is harder and will
machine with minimal tearing or galling. The picts shows the
difference in profile ... less shrouding of the seat, smoother
radius on the edges.
drop it into a Discovery next time I have one apart and see
what happens. I profiled it in a lathe, but the DIY airgunners
could easily chuck one in a drill and profile one on sandpaper
or a sharp file. Stay tuned for results!

started offering free fill cap machining for the Discovery
and Marauder Pistol fill end caps a few years ago, but I never
got around to mentioning it on my website. SO ... if you buy
a TKO Brake that required the fill cap to be machined, send
it in with a short note with your mailing address and for
which air gun it is for. The machining depth is slightly different
for the Discovery than for the Marauder pistol, so be sure
to mention the model.

Benjamin Discovery has been out long enough that we are starting
to see almost all guns that have been in service for 3 years
or more having corrosion in the fill adapter area. Most leaks
we fix are in this area. Here is a recent gun we opened for
A The fix is to remove the o-ring, spin the valve stem in
a drill press or lathe, and polish off the corrosion til smooth.
We also spin the valve seat/nipple and smooth the seating
surface (inset photo.) I have been trying to determine which
guns are most prone to corrosion ... filled from a pump or
filled from a scuba. So far, it's about a toss-up. My
recommendation... spritz some silicone oil in the fill nipple
every once in a while.

My son Billy returned today from 6 months of Army Basic Combat
Training (Ft. Leonard Wood) and Advanced Individual Training
(Ft. Jackson). We had quite a welcome celebration! Billy was
the "brains" behind the TKO Tube Stock and made
a few before he left for training. I guess I'll put him to
work making a few more sets of components before he starts
school in a few weeks. WELCOME HOME BILLY...
I thought I would build up a special Crosman 2240 to benefit
the Wounded Warrior Project. I will start with a stock Crosman
2240, add a Combat 1911 trigger, do an accuracy tune and add
a Special paint scheme TKO Stage V brake. Watch this blog

the works! ... 1911W (Wide).
in the process of making the tooling to finish a batch of
1911W trigger blades for the Crosman pistol trigger frame.
These have a wider finger flange. We'll start with a small
batch of 15, then if all goes well, we'll make a batch of
100. The earlier design has sold very well (100 total). We
cut several with extra waste area to use as clamps. We WaterJet
cut those "inside the path" so the clamp tooling
will fit tightly and not allow the part to "wander"
during machining. Available Mid-August.

like the Discovery air rifle because of the light weight and
lower operating pressures when hand-pumping, but also like
a decent peep sight.
"Industry Brand (IB)" rear sights sometimes available
on the various airgun classifieds can be made into a great
little rear peep sight. I simply glued an extra rear sight
blade from a 1377/1322 to the face of the IB rear sight, then
glued the original discovery front sight to the TKO VMod,
and it works like a charm. The IB rear sights are sometimes
available from Archer

.25 caliber airguns have become very popular, so we set out
to design a VMod specifically for the larger bore. This brake
for the Hatsan BT-65, 25 cal., is 1" diameter and has
a specific spacing of the first 2 stages to help with the
initial impulse. This VMod was built to 7.5" OAL, but
we have found the 6.5" to be nearly as quiet with some

was an interesting project that took forever to complete.
Mike S. Asked me to build up a rifle for his 6 year old son.
We started with a Crosman 2400KT in .177 cal. I exchanged
the airtube for a 2260 tube, getting ready to eventually update
it to PCP. After his son shot it for a few months on Co2 cartridges,
I did the PCP conversion to PCP, did a trigger job on it and
made up a shortened BT Tube stock to fit the tyke. Of course
it also has the TKO Stage VMod in 6.5' length. Mike camoed
the entire rifle and it appears that like Sammy can really
