So I got a second Yokozuna recently and it came with the QD, which I thought to be a nice thing… but then I started shooting. The gun basically turned into a shotgun. Checked the mod for clipping, nothing there (I upsized as well). Got my head scratching so I swapped it with the regular screw-on Yoko I have on another gun. Hole in hole again. Put the QD version on the gun that donated the regular Yoko. Shotgun. Put the QD Yoko on my ghost (usually running a Falx on that one). Not quite a shotgun but 1.5 inch groups plus 3 inch fliers at 50y instead of the usual 1/4-1/2 inch ragged hole. No clipping. So I swapped the cones between the Yokos and all good on the screw-on and all trash on the QD… seems like the QD messes with your harmonics or whatever on shrouded and/or high power guns. Not sure whether that’s already known but thought let you know in case someone is chasing the same issue.

P.S.: anyone needs a QD adapter for a Yoko?

I bought a QD RYU. And yes the pellet the rifle shot well went from good groups to 6”+ groups at 30 yards. The rifle seems to still shoot other pellets pretty well. Unfortunately I loaded up on 28K pellets it liked when there was a great sale. So I have a rifle, which is the only rifle I own that is moderator ready, and a crap load of pellets that now hate the moderator. Big let down. It Is very quiet though. I picked the QD RYU as there are YouTube videos with the exact rifle and moderator that shot great. Glad you posted this. I am curious if others have the same experience and know if there is a way to fix it.

You can buy the the regular endcap. I’ll do that since I know for my gun that the issue is the QD and not the mod as such.

I guess it depends on the gun. I had issues with QD on multiple when I tried. No issues whatsoever w/o QD. Or maybe no issues with ryu since they are a bit lighter than the yoko. Who knows, all I know is that the baffles worked perfect on the screw on yoko but turned 3 guns bad with the QD.

In my case I am shooting a 12fpe .177 rifle. I have only noticed it with one pellet. A pellet the rifle shot well prior to the RYU with QD. Other pellets seem to shoot fine. Just aggravating as I loaded up (went overboard and bought 28K pellets) and now the rifle with the QD RYU doesn’t like them. I have no other rifle I can use it on. I just bought it as I thought it looked cool. Noise isn’t a problem were I live. That’s why I don’t own moderators.

I've equipped my Yokozuna with the Quick Disconnect, and it's mounted on my .308 Texan without any problems at all. 2 shots with 150gr slugs at 100 yards. the tape over the shot was just to market, and then to more from 100 yards.

Complaints like this one adds no value without knowing the cause. All it takes is a straight rod with the same diameter of the barrel lands long enough to reach the barrel plus 2 inches from the mounted moderator. When inserted through the moderator and into the barrel, the rod should exit the moderator in the center of the bore. If it doesn't the moderator is mounted crooked. Now, figure out why that is and then tell the forum.. It should not be a mystery.

Not sure what your point is. I didn’t complain, I simply reported what I observed. I eliminated one variable after the other, there was no clipping whatsoever. Swapped between different rifles. Swapped the baffles between a screw on and QD. The only constant correlating to the issue I had was the QD. No QD, no issue with either set of baffles on any rifle. QD, issue with both sets of baffles on multiple rifles. All of that is stated above… I searched a bit and here you go, apparently even Donny says that QD can be an issue:

Moderator on my FX King. (Yokozuna)

Because of the noise level on my new FX King in 30 caliber, I purchased from Utah Airguns a Yokozuna moderator. I went through numerous video watching on Youtube about this and the quick disconnect. I am experiencing some very severe accuracy issues that I will research later but for now I will...

My guess is that it can cause addition/prolonged vibration and mess with harmonics. Though the important part (to me) is that the screw on endcap solved the issue if anyone is chasing it as welll.

But yeah, great value added by the comment…

My point is simple. You are experiencing clipping and the cause is that the moderator bore is not in line with the barrel. You don't know that because you have no way to detect it. Hence the suggestion of using a test rod. Having a test rod is super convenient and easy to use. It should be used every time a moderator is mounted to a gun. If you own a moderator, you need a test rod. There are many ways that can skew a moderator out of barrel alignment. This misalignment thing is the primary reason moderator manufacturers use over large bore clearances, because they do not want customer complaints. These large bore clearances really hurt the silencing function. If everything was in perfect alignment, you only need a few thousands of clearance. If you doubt me, measure the moderator bore size yourself.

No clipping. As said. The mod is even sized up on the rifle that was the worst with it. Even if there would be magical and invisible clipping (which is easy to spot on a Yoko), it would still be due to the QD since all 3 guns I tested went worse with the QD but were happy with the same baffles on a screw on. But seems like I am just repeating what is already mentioned above so I guess that’s it from me on this. Happy shooting.
