The New CMMG "ZEROED" Suppressors

Impact at the Outpost and ZEROED suppressor overview

The video opens at CMMG’s fourth annual Impact at the Outpost event, held at their outpost range with a long rifle bay stretching out past a hundred yards. The day serves as CMMG’s showcase for new products, since they do not attend SHOT Show. Every gun on the line is suppressed, highlighting how fully they have committed to running their platforms with cans. The focus is on the new ZEROED line of suppressors, which will be tested across various CMMG firearms throughout the range day before a factory tour. The host notes how much the fully suppressed setup improves comfort on the line and sets the stage for hands‑on evaluations.

9mm Banshee and ZEROED 36K performance

The first gun featured is a CMMG Banshee in 9mm, building on CMMG’s reputation for .22 LR conversion systems and proprietary magazines. The Banshee maintains familiar AR‑style controls with a compact action and standard carbine spring. It is equipped with a new ZEROED K‑length suppressor, identified as the ZEROED 36K in 9mm, mounted on a compact brace that gives the gun a Scorpion‑like feel while retaining CMMG’s design cues. Despite range rules recommending ear protection, the host removes hearing protection to better gauge sound and remarks that the short K can still delivers what feels like full suppression. The platform is described as soft‑shooting, well balanced, and easy to handle, with an open‑hub rear design that allows use with existing mounting systems.

.45 ACP Banshee with full‑size ZEROED 46

Next up is a .45 ACP Banshee, a model previously covered in detail on the channel. The host emphasizes how .45 ACP is naturally subsonic, which pairs well with suppression and contributes to a very soft recoil impulse. This Banshee is fitted with a full‑size ZEROED can in the .46 family, referred to as a ZEROED 46, using the same open‑hub design as the smaller models. Even in the full‑size configuration, the suppressor’s overall form factor remains relatively compact and lightweight. The host notes that it would be a practical option for .45 ACP subgun‑style platforms or 300 Blackout setups, describing the recoil as smooth and the shooting experience as comfortable while maintaining CMMG’s familiar ergonomics and sound characteristics.

Descent in 300 Blackout and Mk47 Descent in 7.62x39

Attention shifts to the Descent line, starting with a Descent chambered in 300 Blackout. The host calls 300 Blackout a favorite due to its versatility with both subsonic and supersonic loads. This Descent features a side‑charging design and an SB Tactical brace, and it runs a ZEROED 30‑caliber can that appears to have a heat‑treated, uncoated finish, developing a patina with use. Although it might look like a piston system, the host confirms it is direct impingement with engineering that keeps the system self‑contained. The side‑charging handle can be folded out of the way, making the gun suitable as a compact backpack or truck option. The video then moves to the Mk47 Descent in 7.62x39, using traditional rock‑and‑lock AK‑pattern magazines. Paired with a ZEROED suppressor and a B5 stock, the Mk47 Descent is described as softer‑shooting than a typical AK while retaining the familiar 7.62x39 feel.

Descent in .338 ARC and Banshee/Descent in 300 and 8.6 Blackout

The lineup continues with a Descent chambered in .338 ARC, designed to keep a small‑frame footprint while using this newer cartridge. The host notes that the .338 ARC load being fired is subsonic yet still has noticeably more push than expected. The gun uses .338 ARC‑specific magazines, which are identified on the line as 400 Legend magazines adapted for this role. The video then returns to 300 Blackout with a Banshee using a full‑size CMMG 30‑caliber ZEROED can, emphasizing the cartridge’s flexibility in switching between supers and subs with a simple magazine change and engaging targets around 75–80 yards. Finally, a Descent in 8.6 Blackout is shown as a “bigger, stronger brother” to 300 Blackout. It features a new B5 buttstock and a new can design, with the host commenting on the impressive performance of 8.6 Blackout in this compact Descent configuration.

Steel coyote challenge with the Mk3

A brief segment highlights a friendly range competition involving a steel coyote target set at roughly 300 yards. Shooters use a CMMG Mk3 rifle to attempt hits on the distant steel. The challenge is simple: connect with the coyote target to win a can of tactical bacon. The host notes uncertainty about the rifle’s exact zero, which adds difficulty to the attempt. The sequence underscores the variety of shooting opportunities at the Impact at the Outpost event, moving from close‑range suppressed carbines to mid‑range precision shots while still keeping the focus on practical field use rather than formal competition.

ZEROED suppressor models and core design features

The video then transitions to a sit‑down segment with CMMG engineers David and Darren to discuss the new ZEROED suppressor line. They outline the models: the ZEROED 36K, the ZEROED 5.56K, a 30‑caliber ZEROED can, and the newest addition, the ZEROED 46. All share an open‑hub rear design and are hub compatible, except for the dedicated .22 suppressor, which is too small for the standard hub interface. The cans use a tubeless, laser‑welded stainless construction with clean external welds. The engineers explain that each suppressor ships with two direct‑thread hub mounts. For the 36K, 5.56K, and 30‑caliber versions, these mounts are in 1/2x28 and 5/8x24 thread patterns, covering common rifle and carbine hosts. The ZEROED 46’s exact included mounts are still being finalized at the time of filming.

Hub compatibility, removal tools, and future directions

Further technical details focus on mounting and maintenance. The ZEROED 46 features a 1/2‑inch square drive at the front, while the other three centerfire models use a 3/8‑inch square drive. This allows shooters to use a standard ratchet to break carbon lock and remove a stuck suppressor without specialized sockets, relying only on the wrench interface. The main suppressor bodies are finished with a gas nitride treatment, and the hub mounts receive a salt bath nitride finish for durability. The engineers mention CMMG’s earlier DefCan line, which used 3D‑printed, low‑back‑pressure designs aimed at a more premium segment. In contrast, the ZEROED series is intended to be more accessible and easier for customers to acquire, while still supporting common hub standards. They note ongoing internal discussions about future materials such as Inconel and emphasize a design philosophy that encourages broad suppressor ownership and improved hearing protection for shooters.
