Anyone have a TKO muzzle brake on their QB79 ?

And if so, is it any quieter ?

compensator and it works great. About $30. Wrap it in tape and then put heat shrink tape over that and all you'll hear is the hammer strike. It is larger than the TKO. I have TKOs on my Discos and 2400 KT. Whisper quite so I don't see why one wouldn't be on the QB.
Merry Christmas.

... on all my CO2 and PCP guns that will take them, very quiet, I would not use anything else, they are worth every penny.

That is good news as I'm waiting for my 5" break for my Discovery, If it takes the initial loud pop out, I'm good to go.

I don't know if I can shoot it in my back yard, but if I can that will be great. If it does, I will put one on my '79 too ;- )

Yep, saw that after I had posted ;- ) they are a bit more expensive for sure. On a $105.00 gun that is substantial for me. I'm sure they are very good, but above my $spend level ;- )

The $49.00 for the Disco version was at my upper spend, but on the Disco since I will be using that as a hunting gun only, that cost was worth it.

Visually, it's a fat unit...but it doesn't look too odd on a short barrel tanker.

Did you tape up the barrel or steel shim it and is it pretty secure ?

How much bigger is the compensator dia than the barrel, do you have a lot of slop to take up ?

More variation in the QB diameters, but close to 15mm for either. Something close to .59". Attaches by set screws. Fit on the pictured (shortened) QB 79 barrel just fine.

Some reminders:

1. The first version of the QB78 used a skinnier barrel (14mm). The QB78 Delux, QB 79, and AR barrels are 15mm.
2. Has to line up to bore center. Not all QB barrels have bores that run dead down the middle of the barrel, so if your bore is kind of off center, may have some clipping issues (this would be true for TKO brakes too).
3. Been warned not to try .25 with this compensator, the internal passages are a little too small. Can enlarge them.
4. Have read of the end cap blowing off, but unsure if those events were from clipping or just massive amounts of high pressure air being shot.


No problems using this one...has been on a couple of 15mm barrels.
