Rearden Mfg shows up constantly in suppressor-buying conversations, but it’s easy to misread what the company actually sells. It isn’t a silencer manufacturer, it’s a mounting-hardware and muzzle-device company, and a well-regarded one within that lane. This guide covers who Rearden is, how its Plan B and CAT/TSFX mounting systems work, the current lineup of thread adapters, muzzle devices, and optic mounts the company actually ships, and who should be looking at Rearden versus a can manufacturer.
Who Is Rearden Mfg?
Rearden Mfg is headquartered at 5151 Sunbeam Rd in Jacksonville, Florida. The company’s own site doesn’t publish a formal founding date, so treat any specific “founded in” year you see elsewhere as unconfirmed rather than fact. What Rearden does describe on its About page is a broader manufacturing background in the firearms industry the company says it played a role in the home-gunsmithing movement and in popularizing 80% lower receivers, and that it has produced parts for other firearms companies before building out its own branded product lines. Its stated operating principles are “Be Great,” “Innovate,” “Teach,” and “Own It,” framed around precision machining and problem-solving rather than marketing polish.
Within the suppressor-accessory space specifically, Rearden’s reputation rests almost entirely on its thread adapters and muzzle devices, not on any silencer of its own. Retailers that carry the brand OpticsPlanet, Primary Arms, and a number of NFA-focused dealers list Rearden squarely under categories like “suppressor mounts,” “muzzle brakes,” and “silencer accessories,” not “suppressors.” That positioning lines up with what the company’s own shop shows: every product category on reardenmfg.com is hardware that connects a barrel to a suppressor or an optic to a rail, never a can that houses baffles and reduces sound itself.
That distinction matters for buyers. A suppressor manufacturer like Dead Air, SilencerCo, or Griffin Armament is judged on baffle design, sound and back-pressure performance, and durability under sustained fire. Rearden is judged on a different set of criteria entirely fit tolerances, QD lockup reliability, thread concentricity, and finish durability on a part that gets torqued, mounted, and dismounted repeatedly. It’s a narrower, more mechanical niche, but it’s one Rearden has built a genuine following in among suppressor owners who run multiple cans across multiple hosts.
How Rearden’s Mounting Systems Work
Rearden’s core business is built around two proprietary-but-open mounting platforms: Plan B and CAT/TSFX. Both are taper-mount systems, meaning the suppressor locks onto a muzzle device via a machined taper and a quick-detach mechanism rather than being threaded directly onto the barrel. The appeal is speed and flexibility a shooter can leave a Rearden muzzle device (a flash hider or brake) permanently mounted to the barrel, and then attach or remove a suppressor in seconds using a matching thread adapter, without re-indexing or re-torquing anything downstream on the barrel itself.
The Atlas line of adapters is Rearden’s implementation of the Plan B interface and is built to accept suppressors with a 1.375″-24 TPI rear thread pitch a mounting standard shared by cans such as Dead Air’s Nomad and Primal, SilencerCo’s Omega 300 and Hybrid 46, YHM’s Turbo and Resonator, and Otter Creek Labs’ Polonium, among others. Rearden also markets Atlas variants as compatible with several other quick-detach adapter standards circulating in the market, including HUB, Charlie, Helios, and Wolfman patterns, which is why the Atlas catalog is split into so many sub-variants rather than a single SKU. The CATlas line serves the same function for the CAT/TSFX interface, a separate taper-mount standard used by another slice of the suppressor market. In both cases, Rearden isn’t inventing a closed ecosystem that locks buyers to its own cans because it doesn’t sell cans it’s building the connective hardware that lets a given muzzle device work with suppressors from other manufacturers.
The Full Rearden Mfg Lineup
Because Rearden doesn’t sell suppressor cans, the table below is scoped to what the company actually manufactures and sells: thread adapters, muzzle devices, and its Argos optic-mount system. “Compatible Calibers/Hosts” reflects the suppressor mounting standard or bore/thread size each product is built around, not a caliber of ammunition fired through it.
| Category | Model | Compatible Calibers/Hosts | Notable Feature |
|---|---|---|---|
| Thread Adapter (Plan B) | Atlas Gen 2 | 1.375″-24 TPI hosts (Dead Air, SilencerCo, YHM, OCL, etc.) | Standard-length Plan B adapter; also offered in a Titanium Gen 2 version |
| Thread Adapter (Plan B) | Atlas XL | 1.375″-24 TPI hosts | Extended-length variant for hosts requiring extra clearance |
| Thread Adapter (Plan B) | Alpha Atlas | 1.125″-28 thread hosts, Plan B-compatible | Heat-treated finish; alternate thread pitch from the standard Atlas |
| Thread Adapter (Plan B) | Wolfman Atlas / Wolfman Atlas XL | Wolfman QD-pattern hosts | Built to the Wolfman adapter standard rather than stock Plan B |
| Thread Adapter (Plan B) | Helios QD Atlas / Helios QD Atlas Titanium | Helios QD-pattern hosts | Built to the Helios QD adapter standard; titanium option for weight savings |
| Thread Adapter (Plan B) | Odessa Atlas | 1.375″-24 TPI hosts | Lower-cost entry point in the Atlas family |
| Thread Adapter (CAT/TSFX) | Charlie Atlas Gen 2 (CATlas) | CAT/TSFX-pattern hosts | CAT/TSFX equivalent of the standard Atlas; also offered in Titanium |
| Thread Adapter (CAT/TSFX) | CATlas Charlie XL | CAT/TSFX-pattern hosts | Extended-length CAT/TSFX adapter |
| Muzzle Device | FHD Flash Hider | Rifle calibers; Plan B mounting point | Flash hider that doubles as the fixed Plan B muzzle device |
| Muzzle Device | SPB Muzzle Brake | .280/.375/.50 bore options; multiple thread pitches (1/2-28, 5/8-24, 11/16-24, 14×1 LH, 9/16-24, SR25/M110) | 17-4 PH stainless, black-nitride finish; Atlas/Atlas XL and Plan B compatible |
| Muzzle Device | R2S Flash Hider | Multiple bore/thread options; tapered, square, or facemount styles | 17-4 PH stainless flash hider built around the Atlas/Plan B interface |
| Optic Mount | Argos | N/A — optic mounting system, not caliber-specific | Available in Black, FDE, and Olive Drab Green finishes |

Rearden’s online shop also lists a small assortment of suppressor-adjacent tools and accessories like alignment aids and thread protectors among them and merchandise like shirts and hats. Those are worth knowing about if you’re already ordering from the site, but they aren’t core to Rearden’s identity as a mounting-hardware manufacturer the way the Atlas, CATlas, and muzzle-device lines are.
What suppressor users would benefit from Rearden Mfg
Rearden makes the most sense for suppressor owners who already have a can or plan to buy one from a brand like Dead Air, SilencerCo, YHM, or OCL and want a quick-detach mounting solution rather than a permanent direct-thread setup. It’s also a natural fit for anyone running multiple hosts (say, a hunting rifle and a range gun) who wants to move a single suppressor between barrels quickly, or for shooters who’ve standardized on a specific QD ecosystem like HUB, Charlie, Wolfman, or Helios and need an adapter built to that exact spec.
Rearden is the wrong starting point for anyone shopping for the suppressor itself the sound-reducing can with baffles inside — since the company doesn’t manufacture one. It’s also not the right pick for shooters who prefer to keep things simple with a direct-thread mount and no additional QD hardware in the chain, since every Rearden mounting system adds a part (and a small amount of length and weight) between the barrel and the suppressor. For those buyers, the suppressor itself, not the mount, is the more important research topic.
Frequently Asked Questions About Rearden Mfg
Does Rearden Mfg make suppressors?
No. Rearden Mfg manufactures the muzzle devices and quick-detach thread adapters that suppressors mount to — including its Atlas and CATlas adapter lines, flash hiders, and muzzle brakes — but it does not sell a suppressor can of its own. Suppressor buyers still need to purchase the actual can from a manufacturer like Dead Air, SilencerCo, YHM, or another dedicated silencer brand.
What is the Rearden Plan B system?
Plan B is a taper-mount quick-detach system built around a fixed Rearden muzzle device (a flash hider or brake) and an Atlas-series thread adapter. It lets a suppressor with a compatible 1.375″-24 TPI rear thread lock onto the barrel and be removed in seconds, rather than being permanently threaded on. Suppressors from Dead Air, SilencerCo, YHM, and Otter Creek Labs are among the hosts commonly mounted this way.
What’s the difference between Atlas and CATlas adapters?
Atlas adapters are built for Rearden’s Plan B mounting interface, while CATlas adapters are built for the separate CAT/TSFX taper-mount standard. They’re not interchangeable — buyers need to match the adapter to whichever mounting system their muzzle device and suppressor host actually use.
Where is Rearden Mfg located?
Rearden Mfg is headquartered in Jacksonville, Florida. The company’s own site does not publish a specific founding year, so any date circulating elsewhere online should be treated as unverified.
Can I use a Rearden adapter with any suppressor brand?
Only with suppressors that use a matching thread pitch and mounting standard. The Atlas line is built around the common 1.375″-24 TPI rear thread found on many Dead Air, SilencerCo, YHM, and OCL cans, plus compatibility with HUB, Charlie, Helios, and Wolfman QD adapter patterns. Always check your specific suppressor’s rear-thread spec and QD standard against Rearden’s published compatibility before ordering.
Does Rearden make anything besides thread adapters and muzzle devices?
Yes. Beyond the Atlas and CATlas thread-adapter lines and its flash hiders and muzzle brakes (like the FHD and SPB), Rearden also produces the Argos optic-mount system and sells a small lineup of suppressor-related tools and accessories.
Because Rearden’s business is mounting hardware rather than cans, it’s best used alongside — not instead of — research into the suppressor itself. Our complete suppressor manufacturer directory is a good starting point for evaluating brands like Dead Air, SilencerCo, and YHM whose 1.375″-24 TPI cans commonly pair with Rearden’s Atlas adapters. If you’re building out a .308-class rifle setup, our best .308 suppressors guide covers hosts that frequently run on Plan B or CAT/TSFX mounts, and our Griffin Armament suppressors guide is a useful comparison for a brand that, unlike Rearden, builds both muzzle devices and suppressors in-house.
