Selecting a length for your LDC/Muzzle Brake:
As a general rule, the length of the brake should depend on your intended use and your airguns power level:

#1: A hunting gun that may be dragged through the brush would benefit from a shorter brake. The 5" TKO Brake still has good performance but is sturdy and makes for a more compact application.

#2: A dual purpose target and hunting gun can benefit from a longer brake. The 6.5" Stage V brake is the most popular brake we make and sell. The longer brake offers improved performance without being overly fragile and prone to mis-alignment.

#3: 7.5" brake (We have discontinued the 7.5" brake. The added performance wasn't worth the extra length and alignment trouble some experienced.)

Available Now! Pre-Machined Discovery Rifle and Marauder Fill Caps

Fsion
We have offered free fill cap machining of customers caps,
but will be discontinuing that service in the near future ... BUT my son James (Lt. US Army, Medical School) has come up with a way to precision cast new fill caps from a master he produced. They have a carbon fiber inset cast into the cap to match the TKO brakes finish. They fit and work exactly like the original fill cap but allow the attachment of the TKO brake to the Discovery rifles and Marauder Pistols. Offered as a set for $61 shipped to USA and PR addresses. ($67 USD shipped Internationally.)

A TKO Half-Shroud for the Umarex Fusion Co2 rifle (AKA XS60)

FsionA 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:

"I 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 could do.
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
10.1011 fps
11.1004 fps
12.995 fps
13.983 fps
14 974 fps

End fill: 1700 psi

Average velocity: 995fps

Ave energy (25.4gr): 56 fpe

AAs200
The AAs200/CZs200 air rifle is a great little target gun and can be made very quiet with the TKO Stage V brake made specially for it.

The TKO brake can be fitted so that the airtube can be removed for filling without removing the brake, even with the longer airtube.

stem1A 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.

stem2I'll 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!

We 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.

This is the target I use to test our Discovery Tunes. It is based on the ARA Rimfire target sized down for the 20 yards I test at. Feel free to download and use and change for your uses. It is a 3 MB jpg file, so download times might be 2-4 minutes.

The 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 the last gun we opened for a tune:

valve

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.

HOME AT LAST!

BT 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...

So 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 for details.

A nice message today:

The LDC arrived today. The fit was perfect. Threads were tight and smooth. LDC flat oversize just about .5mm in diameter as planned. I am very pleased.
Thanks,
William.

trigIn the works! ... 1911W (Wide).

We're 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.

Did you know...

r

the TKO Stage V brake for the Discovery/22xx airguins also fits the newer Crosman Tactical pump airguns? I prefer the shorter 5" for these guns, but the 6.5" makes them VERY STEALTHY!


Thursday, July 25, 2013...

rI like the Discovery air rifle because of the light weight and lower operating pressures when hand-pumping, but also like a decent peep sight.

fThe "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 brake, and it works like a charm. The IB rear sights are sometimes available from Archer Airguns.

hatThe .25 caliber airguns have become very popular, so we set out to design a brake 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 brake was built to 7.5" OAL, but we have found the 6.5" to be nearly as quiet with some length savings.


Tuesday, July 23, 2013...

samThis 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 V brake in 6.5' length. Mike camoed the entire rifle and it appears that like Sammy can really shoot.


Monday, July 22, 2013 ... If you received a Discovery or Crosman 22xx brake from us last week and it fits loosely to the barrel, we have a replacement for you. We sent a recall message to those affected. (8 total brakes are in that batch.) Send an e-mail and we'll get a replacement sent along with a mailer label to return the incorrect brake.

Mailserver back up and running. If you sent e-mail over the weekend and didn't receive a reply, please re-send.
