About Zastava & ZVuk
Perhaps best known today for its line of M70 ZPAP AK rifles, Zastava has a long history of making quality military firearms that goes back to 1853. It was the cornerstone for military arms production during the Cold War for the Socialist Federal Republic of Yugoslavia.
Based in what is now Serbia, Zastava continues to churn out new firearms and, now, suppressors to go with them.
I’ve personally tested Zastava’s ZPAP rifles, and I am a huge fan. Aside from the rock-solid reliability and good looks, these guns are well-priced for the high-quality construction, especially in today’s increasingly pricey AK economy here in the States. My personal ZPAP was used for most of my testing in this article, with zero malfunctions using standard ammo.
To the best that I can figure, the new 3D-printed titanium Zastava ZVuk name appears to come – at least in a togue-in-cheek kind of way – from the Serbian "zvuk" (звук), meaning sound or noise. That’s not explicitly stated, but it’s an explanation that I enjoy. While it is a Zastava product, the ZVuk is produced on behalf of Zastava Arms USA for the U.S. market, and not simply as a Serbian export accessory.
It shares a rough profile similarity with the iconic Soviet PBS-1 AK suppressor from the 1960s. That Cold War can was used extensively by the Spetsnaz and KGB, and Zastava has significantly updated the design and build materials for the modern era.
On that note, let’s dive into the features of this unique suppressor.
Features & Suppression Rating
Coming in at just 13.4 ounces, the titanium Zastava ZVuk suppressor has a monolithic, 3D-printed body-to-core structure purpose-built to reliably suppress and cycle AK platforms chambered for 7.62x39mm. It can handle other chamberings that fall into .30-caliber sizes and below, but the AK is where this can was made to thrive.
In fact, the ZVuk is full-auto rated, even for the hot and gassy AK platform.
It features a patented Purposefully Induced Porosity (PIP) internal structure that differs from the original Soviet PBS-1 AK suppressor and modern lookalikes, such as the Dead Air Wolverine. Instead of simply using stacked or stepped baffles, the ZVuk increases gas flow rates with a combination of stepped baffles and the PIP’s lattice of controlled pores to further vent and redirect gas.
The PIP design gives the ZVuk multiple flow paths for gas. The impact, according to my own ears on the range, is “significantly higher pure suppression performance from the ZVuk, with a higher gross flow rate.”
Pew Science gives the ZVuk a Suppression Rating of 33.7. You can compare that to its peer competitor, the Wolverine, which sports a 23.5 rating.
There is a lot that goes into those suppression ratings, so we can only take that as a limited data point. Pew Science is a wonderful resource for those who want to dig far deeper than we have time to here. Regardless, the ZVuk is a clear step above simpler baffle designs.
Zastava itself claims a potential 32-decibel reduction, which is a feat for such a short can on a loud gun like the AK platform.
As an AK suppressor, the ZVuk comes with a direct-thread M14x1 LH HUB adapter, and its HUB compatibility makes it ready to run on other thread types for firearms with chamberings of .30 caliber or below (i.e., 7.62mm and down). An M26x1.5 LH direct-thread HUB adapter is available as well.
While typical AK threads run in a left-hand twist, the HUB is a standard right-hand 1.375x24 TPI. That means you won’t simply twist the suppressor tube off the HUB threads when removing the suppressor from an AK, which is another win that makes this can easier to install and remove.

Range Testing & Video Demos
The video above is a quick demo of how the ZVuk performs with standard, supersonic 123-grain 7.62x39mm ammo. I have run a wide range of non-subsonic ammo through this can on my Zastava ZPAP, Zastava NPAP, and Arsenal SAM7SF.
After 500 rounds of testing, I have not seen anything that would be considered a suppressor-induced malfunction with standard AK ammo.
What is harder to see in that video is just how much the ZVuk cuts down on felt recoil and, significantly, gas blowback. AK-pattern guns have a large gas tube that cycles a large action. This necessarily makes the platform inherently loud when compared to more closed-off operating systems.
Past testing has demonstrated that just manually racking the bolt on an AK can peak sound meters at more than 80 decibels. That’s essentially the same as having someone yell right next to your ear.
Further, other baffle-only suppressors I’ve tested resulted in significantly higher levels of gas and debris hitting me in the face. The ZVuk is downright pleasant by comparison because it redirects gas better, moving it through and out the end of the suppressor via multiple paths.
Similarly, the felt recoil is noticeably less than with a standard AK slant compensator or no compensator at all. Here’s a demo of the same rifle unsuppressed.
The true noise level does not translate well on video, but you can still sense how much louder the above shooting was without a suppressor. You can easily hear the gunshot echoing into the distance without the ZVuk.
For those curious about subsonic ammo, which is rarely easy to cycle in AKs, I happened to have some 182-grain PPU subsonic 7.62x39mm ammo on hand. Here is what I got when testing that.
That specific subsonic ammo was quiet enough for me to hear the bullets impacting the berm 50 yards away. However, there was not enough gas pressure to reliably cycle the rifle during my testing, and you can hear me manually racking the gun.
If you want to run subsonic rounds through this suppressor on an AK-pattern gun, you will likely need to tweak the gas system. For my money, the effectiveness of the suppressor with standard ammo is enough to skip finicky subsonics altogether.
Pros & Cons
Here’s my short list of the pros and cons of the ZVuk suppressor.
Pros:
- Good sound reduction for the loud AK platform
- Very reliable with standard 7.62x39mm
- Lightweight and strong titanium construction
- Reduced backpressure and felt recoil
- Optimized for the AK platform
- Comes ready for AK-pattern M14x1 LH threads
- Full-auto rated
- Cool, classic looks
- Compact size
- Reduced felt recoil
- Easy to clean
Cons:
- Won’t cycle subsonics without tweaking or further testing
- Hearing protection still highly recommended
-
Competitively priced, but not cheap
Final Thoughts
At a glance, the ZVuk may look like a classic AK suppressor straight out of the Cold War, but the 3D-printed titanium construction with Purposefully Induced Porosity tech is cutting-edge. This suppressor cuts noise, backpressure, gas blowback, and felt recoil better than any other cans I’ve personally tested on my AK rifles, and it looks good doing it.
On top of all that, it’s lightweight, short, and HUB compatible. You will need to shell out some cash for this quality quiet can, but it is robust enough to cover you for extensive shooting sessions for years to come.
