Considering getting a suppressor for my Yugos, looking at multi-calibers as well. I'm a newb to the suppressor world. Thanks for any help!
 
Yugo as in AK?

Yeah my personal opinion is that the AK in 7.62x39 is a terrible suppressor host. That is said as a Yugo AK afficianado. The AK pistol is perhaps the worst, and why I own a .300blk 8.5" pistol.

If the commie rifles are your main concern, just get a Dead Air Wolverine and be done with it. ;)

Beat me to it. The Wolverine PBS-1 paired with a KNS Precision adjustable gas piston(s) for your gun(s) will make them run like sewing machines.

Yeeeppp. Only way to go for AKs.

And DO NOT expect to fire in without ear protection more than a couple times ... especially at an indoor range or even when under a shelter at an outdoor range. It’s borderline line hearing safe (just over 140dB) and will still ring your ears especially in the pistol configuration.

Is that because it's piston operated?

That is a large part of it along with the sonic crack. It’s not to bad in the open for a few rounds and just simple foam plugs will tone it down nicely for more extended fun.

ETA: touching off suppressed AR’s, especially in SBR or pistol configuration, is not much lower indoors or under a covered range line. They might be 5 or so dB lower but they will still have a fair report and the sonic crack. Running a suppressed SBR in a shoot house and having your ear protection knocked off will cause you to stop real quick.

Gotcha, I’m not familiar with AKs, I’ve a 300BLK AR SBR, other ARs and 5 cans. I haven’t shot any of them indoors or in a shelter.

The only suppressed SBR I’ve felt comfortable with firing in a shoot house with no hearing protection is a .300BO with subsonics and the report still did bounce around enough to be loud ... no deafening but enough to take a break regularly.

You’re not far from Fuquay Gun. They are a class 3 dealer and can hook you up. They’ll do the paper legwork in the price of the can.
 
5 dB is huge in perceived loudness above 125dB...huge! I learned that in IASCA competition many years ago. The AK is just loud af
The dB scale is not linear ... it’s exponential type function ... as Ikarus points out a small dB can be a huge “loudness” increase depending on where you fall on the scale ...498C27B9-96BE-45BE-BAED-701243D10AB8.jpeg
 
The only REAL way to suppress an AK is the way Aklys Defense did it with their AKSV. I say that will lots of love for the platform. It just wasn't a system consideration in 1945 when the AK was on the drawing board.

and some of this:

I've suppressed many AK's for customers and it's underwhelming when you hear what the AR/300BLK combo achieves with the same suppressor unit on the front. I still use them and love them for flash hiding and low light training to maintain vision.
 
I'm not sure. I missed the piston AR phase but it's never apples to apples when comparing the two systems.

There are subsonic loads for the AK that will cycle the gun with no issue and will keep the perceived report as quiet as a properly suppressed AR15 in 5.56 with supersonic ammo. The 3,000fps 5.56 cracking the sound barrier is loud and suppressor can't address that issue. There is no subsonic 5.56 that can reliably cycle an AR15 in DI or piston to my knowledge.

Will a 7.62x39mm piston AR15 be as loud as an AK when using the same suppressor and ammo? Hum....

I picked up an AA 16" 5.56 to try one of my cans on it. I need to get a TBAC barrel adapter.
 
I plan I getting the Griffin adapter to run on my 74 with the hybrid. Seems to be safe enough, baffle strike wise. Volume not expecting too much.

Basically ak barrel threading isn't exactly the most precise. Cause it doesn't have to be for a brake. So options are larger caliber suppressor, the wolverine, or if possible getting the barrel cut and rethreaded if it's a pistol, or a longer than standard ak.

Others have touched on the other issues with suppressing an ak. I've heard some that were dumb quiet, but the work involved is kinda intense, and those were so built out for subsonic they didn't run supers anymore. Not safely anyway.

I would highly recommend a professional cut/concentric thread job or replacing the barrel.

The KNS adjustable piston has changed the game regarding running different ammo reliably. Brown Bear manufactures x39 subs now that will cycle in a standard 16” AKM.

I can attest to this with a few of my can-worthy AK-patterned guns. There have been a few reports of questionable QC but that may be limited to certain batch numbers. One guy I know bought a 500-pack on sale from KVAR, ran into issues, and KVAR sent him another 500-pack. No issues with that second batch.

I would highly recommend a professional cut/concentric thread job or replacing the barrel.

Piggybacking on the notion of concentricity, if anyone has looked at bore alignment rods (~$75+), a far cheaper and just as effective option IMO is a tool steel rod from McMaster-Carr or Fastenal (~$7). Also, maybe it's because I'm an AK guy and we live a bit more loosely, but it doesn't get much easier than removing a bolt, staring down the suppressor or muzzle device and looking for a perfect circle of light on the other end.

Most ak barrels are too short to just cut and rethread. Unless you are pinning and welding a muzzle device on.

That piston is pretty solid though, I have played with them in the past, and if I had a 47, would be my preferred choice with that ammo, but since I run the 74, I doubt any subsonic ammo exist.

But, that also means I don't have to fret too bad about the hybrid on it. Given the round is half the size of the suppressor bore. If it is that bad off it will be quite visible.

I have done that before with an AK builder and our eyes fooled us as a baffle strike soon followed. Not a fun realization.

Have not tried it but there are some YT vids featuring the stuff. On the product page it states "This ammunition intentionally does not cycle the action, for the ultimate in quiet shooting. Each round must be manually ejected." which to me is marketing mumbo jumbo for "I don't work as well as I'm supposed to."
 
Don’t get a suppressor you’ll only have remorse especially next to your buddies .300 BO at the range. However, you can get a smidgett or sound moderator to address muzzle blast and knock a few db off. And it looks cool.Krink it. Every ak at the range, with enough use, will suffer a strike. Fwiw good luck
