I sum up 2025 to be the year of the silencer. There has never been a better time than now to get a silencer, or even multiple silencers. Wait times are the shortest they’ve ever been in the history of the ATF. And, come January 1, 2026, thanks to the Big Beautiful Bill, the $200 tax stamp requirement will change to $0. That said, I don’t recommend waiting until January to buy a silencer. With this bill passing, the demand for silencers is expected to skyrocket, potentially leaving many brands, if not all, struggling to keep up with inventory. You can purchase all the silencers you want now and wait until 2026 to complete the tax stamp paperwork for $0.
With so many options of silencers on the market today, it can be a challenge to keep up with what’s new. One of the more recent releases of new silencers is from Israel Weapon Industries (IWI). In April 2025, IWI announced its line of silencers and showed them to the public at the 2025 NRA Annual Meeting. The line-up consists of five silencers, built to high-performance standards for military, law enforcement, and civilian shooters. I was able to get my hands on the complete set to test out at Tennessee Silencer while I wait for January to roll around.

Universal Features of the IWI Silencers
Reduced Pathogen Silencers
The unique aspect of the new silencers is that they feature a reduced pathogen design to minimize a shooter’s exposure to toxic gases. If you’ve ever shot a suppressed rifle and swallowed a bunch of gases, and had your eyes watering profusely, then you will appreciate this design. I experienced none of that with each one of the IWI silencers. This design also benefits the firearm by helping to maintain a smooth cycling operation and reducing the wear on parts.
HUB+ Adapter & Reverse Compatibility
The toughest decision, after choosing a silencer, is how you intend to mount it to a gun. You can direct thread the thread straight onto the barrel, use a QD-style mount, or utilize any of the existing HUB systems. The thread pitch pattern of your barrel is essential to know so you end up with a compatible mount or direct thread solution.

IWI ships its silencers with a HUB+ attachment and a wrench to easily direct thread each silencer onto a gun or remove the IWI HUB+ attachment from the silencer. IWI designed its lineup of silencers to be reverse-compatible with existing HUB systems, making it even easier for the end consumer. There’s also a dedicated website page featuring approved adapters and mounts for use with IWI silencers for warranty purposes. Not all manufacturers make it this easy for the end consumer, especially when it comes to compatible mounting attachments and systems. Some manufacturers design their products to be compatible only with mounts they manufacture, thereby generating additional revenue from accessories.
Now let’s get into the nitty-gritty of each one.

IWS22
In my opinion, the best way to introduce firearms to young children or newer shooters is to have them shoot a suppressed 10/22 rifle. The complete lack of recoil and the gun’s virtually silent operation make it much less intimidating for a newer shooter. This is also why I recommend that many people start their silencer collection with a rimfire silencer, especially one that is compatible with multiple rimfire calibers.
The IWS22 silencer is compatible with .22LR, .22WMR, 17HMR, and 5.7×28 calibers. It uses the common 1/2×28 thread pitch pattern to direct mount onto a matching thread pattern barrel. The IWS22 is made from Grade 9 titanium and 7075 aluminum and is hand-assembled atthe factory. Compared to similar full-auto-rated .22 LR silencers on the market, the IWS22 is lighter, albeit with a slightly longer design, but is ultimately less expensive.

I paired this silencer with two of my Volquartsen Firearms: a .22 LR rifle and a .22 LR caliber pistol. It sounded like a BB gun being shot. And, because it’s full-auto rated, you can mag dump as fast as your heart desires without fail. The overall weight of just six ounces makes it very reasonable to add to the end of a pistol or rifle. Heavier silencers can make it more challenging to hold the gun upright and may even cause the muzzle to dip slightly downward inrecoil. With its price point being more competitive than similar silencers I own, I would recommend this one for its affordability and quality.
IWS22 Specifications
- Caliber: .22
- Muzzle Attachment: 1/2×28 Direct Thread
- Length: 6 inches
- Diameter: 1.19 inches
- Weight: 6.0 ounces
- Materials: Grade 9 Titanium & 7075 Aluminum
- Full-Auto Rated: Yes
- MSRP: $439.99
IWS6
The IWS6 silencer will perform best when paired with a 6mm caliber rifle. It’s also an excellent solution for 5.56 NATO, .223, and .224 caliber rifles. IWI designed this silencer to be compatible with user-changeable end-caps. The included vented cap helps maximize gas flow, while a closed cap (not included) sets the silencer up for superior sound reduction. This silencer is full auto-rated, built with weapon-grade nickel alloy and stainless-steel components. It is also CNC laser-welded, making it rugged enough for use on short-barrel rifles as well. The IWS6 utilizes IWI’s Hub+ attachment, featuring a 1/2×28 thread pitch pattern, which makes it easy to mount on compatible barrels.

I mounted this silencer on my custom-built bolt-action rifle, chambered in 6mm Creedmoor with a Bartlein Barrel, and housed in a Magpul Pro 700 chassis. This is one of the rifles I use to compete in the Precision Rifle Series. I have only ever shot suppressed in this style of competition, never with a muzzle brake. A suppressed rifle reduces the sound, but it also eliminates much of the felt recoil without the expulsion of gases to the side. I currently use a very long silencer and find it cumbersome when moving an already long rifle in and out of corrugated pipes or windows. The IWS6 is shorter and still provides the reduction in sound and recoil that I’m looking for.
IWS6 Specifications
- Caliber: 6mm
- Muzzle Attachment: HUB+ Mount, 1/2×28
- Length: 6.4 inches
- Diameter: 1.74 inches
- Weight: 18.0 ounces
- Materials: Nickel Alloy & Stainless Steel
- Full-Auto Rated: Yes
- MSRP: $779.99
IWS6K
The IWS6K silencer is a lighter and shorter design of the IWS6. If a silencer is labeled as a “K” can, that typically means it’s a short silencer. There is no set definition of a K length, but most average between 4.5 and 5.5 inches. The 6K silencer measures 4.9 inches and weighs 14 ounces, compared to its larger counterpart, the 6 silencer, which measures 6.4 inches in length and weighs 18 ounces. Other than those two changes, it features the same muzzle attachment, is made of the same materials, and is still full-auto rated.

This “K” length silencer was my favorite of the collection because of how much it surprised me in terms of performance. I don’t own any K cans, nor do I find them as effective as I’d like them to be, sound and tone-wise. That’s why this silencer gave me pause after I shot a few rounds through it and found it genuinely pleasant to shoot. I mounted this to the Dark Storm Industries Modern Fighting Rifle, as it’s my go-to ambidextrous AR-15 that is a great suppressor host. I started with 55-grain ammunition and then tried different 77-grain ammo through the gun and silencer combo. The 77-grain loads all sounded phenomenal through the K-length silencer. This is the ideal silencer for competitions that permit it and for use on a home defense carbine.
IWS6K Specifications
- Caliber: 6mm
- Muzzle Attachment: HUB+ Mount, 1/2×28
- Length: 4.9 inches
- Diameter: 1.74 inches
- Weight: 14.0 ounces
- Materials: Nickel Alloy & Stainless Steel
- Full-Auto Rated: Yes
- MSRP: $729.99
IWS7
The IWS7 silencer was designed for use with 7.62 NATO and 7.62 magnum rifle calibers. The IWS7 essentially is the same offering as the IWS6 silencer, only with a change in muzzle attachment thread pitch pattern and caliber rating. I also mounted this silencer onto the Modern Fighting Rifle because I usually “size up” on suppressor caliber ratings to something that can handle more than I plan to shoot. That’s why I also typically recommend 30-caliber silencers to people who want to use one on multiple rifles, or who have a 30-caliber gun in addition to a .223 or 5.56.
To no surprise, it sounded great to shoot and had a nice tone, which is subjective to the individual. What was extremely convenient was that I took the IWI Hub+ attachment from the IWS6 and swapped it with the one that came with the IWS7. Within seconds, I transitioned from a 5/8×24 mount to a 1/2×28 mount to make it compatible with the .223 caliber rifle. Overall, this is a great silencer for individuals who want the option to shoot higher-caliber rifles.
IWS7 Specifications
- Caliber: 7.62
- Muzzle Attachment: HUB+ Mount, 5/8×24
- Length: 6.4 inches
- Diameter: 1.74 inches
- Weight: 18.0 ounces
- Materials: Nickel Alloy & Stainless Steel
- Full-Auto Rated: Yes
- MSRP: $849.99
IWS7Ti
The most unique silencer from IWI is the IWS7Ti. If you’re looking to suppress a high-powered gas gun or a hunting or precision rifle bolt-action gun, the 7Ti is what you want. This silencer is constructed with Grade 5 and 9 titanium internals, reducing its weight to 13 ounces. The length of the silencer is 7.4 inches, which is comparable to or shorter than similar silencers designed for long-range shooting rifles.
A silencer is a must-have when it comes to hunting. You need to be able to hearenvironmental sounds and listen for potential prey, but also be ready to take a shot quickly without having to find your hearing protection, which could potentially spook the animal. And, if you’re hunting with others or even sharing a blind, the polite thing to do is to shoot suppressed. There is no option to forego hearing protection just for the sake of hunting.
If you’re an avid hunter, then you know that every bit of gear you bring means additional weight to carry. This is where lightweight rifles, scopes, and silencers are the key to success and comfort. I mounted the IWS7Ti to my CVA Cascade rifle chambered in 6.5 Creedmoor. This rifle comes with an incredibly impressive muzzle brake that drastically reduces felt recoil, but it’s just as effective when shooting suppressed. The titanium baffle system still performs great even with the drastic weight cut from the IWS7. A word of caution to anyone new to titanium silencers: they can get extremely hot quickly. This is the only silencer in IWI’s line-up that is not full-auto rated (which, when you’re hunting, you shouldn’t need anyway).
IWS7Ti Specifications
- Caliber: 7.62
- Muzzle Attachment: HUB+ Mount, 5/8×24
- Length: 7.4 inches
- Diameter: 1.74 inches
- Weight: 13.0 ounces
