TKO info, learn from my mistake

[niclaw]

I recently damaged my TKO muzzle brake.  Comparing my 2300S without and 2240 with a muzzle brake, it is easy to "hear" when the 2300S is getting low on CO2, not so easy on the hushed 2240.  What likely happened is that when the CO2 was low a pellet failed to exit, new cartridge and then next pellet and stuck pellet tumbled around inside the brake and damaged the internals. So be aware and if the slightest doubt safely check for an obstructed barrel.
Many thanks to TKO for taking care of it.

Now that is a weird thing that happened to you. I have never experienced this, but could see this happening if you do not keep track of your pellets. I rarely shoot a cartridge to dead empty, rather I bleed it off shortly after the POI begins to drop.

I always seperate 40 pellets before I shoot with my TKO so this doesn't happen but can see how it could.

There you go.

I agree with Larry, POI drops a little I change the cartridge.  CO2 powerlets are cheap.

I usually wath for POI change also then pump my guns up. But one good point brought up here is when you first put a gun together dont put a tko on it until youve check fired it first. While building my 2250 I pumped the gun up and fired with the pellets hitting about 5 inches low at 10 ft! That would have caused this same problem if I would have installed my tko break on first test fire. Glad TKO took care of you, thats a testament to the company.

as long as the ldc is correctly aligned with the barrel no damage will occur even on a new build
shooting 5" low at 10' is a sight issue not a barrel-ldc problem imho but sometimes better safe than sorry

That's a really great point. I only have a TKO on a 1377 for now, but would like one on my 2240 too when funds come in some day.
he TKO is really tight on the 1377, I can't see how you could just take them on and off easily. I even lightly smeared Pelgunoil on the end of the barrel first.
Any tips to make it easy to put on/remove?

Find a wooden dowel, any kind of round stock will do. Get some nice silicone carbide (black) sandpaper. wrap it around the round stock a few times. The number of wraps will be trial and error, just cut some off if it's to tight to inset into the TKO. spin it around a few times, blow/wipe out the dust and check the fit.  Keep doing it till you like it

What is the TKO made of where the barrel fits in? Aluminum? If you can remember, what grit did you use?

iirc the end caps are delrin same with the internals and the tube is aluminum

Thanks Ed.
and thanks for posting this thread niclaw. You will probably will save some people future headaches.

I used 400 grit silicone carbide Tater, not wanting to cut aggressively.
