Rearden
The Rearden Calico .375 1/2x28 muzzle device is a tapered-shoulder suppressor adapter built for shooters running CAT or TSFX-compatible suppressors on their centerfire rifles. With a .375 bore and standard 1/2x28 thread pitch, it threads directly onto common rifle barrels—making it a straightforward, no-fuss connection point between your barrel and suppressor. The nitride finish resists corrosion and handles the heat cycles of regular shooting without degrading, so you can rely on it through seasons of hunting, range work, or tactical shooting.
If you're already invested in a CAT or TSFX suppressor ecosystem, this adapter simplifies the mounting process and keeps your setup modular. The tapered shoulder design seats the suppressor securely and consistently, which matters when you're counting on zero shift between suppressed shots. It's not flashy—it's just solid engineering that does what it's supposed to do every time you shoot.
The nitride finish is a practical touch for field use. It stands up to solvents, carbon fouling, and weather better than bare steel, so you won't be babying it in your gun safe. Whether you're suppressing a .308, 6.5 Creedmoor, or another common rifle caliber, this adapter fits standard 1/2x28 barrels and keeps your suppressor mounting consistent and repeatable.
| Brand | Rearden |
| Product Line | Calico |
| Thread Pitch | 1/2x28 |
| Bore Size | .375 |
| Suppressor Compatibility | CAT / TSFX |
| Finish | Nitride |
| Color | Black |
| Design | Tapered Shoulder |
The Rearden Calico is designed for CAT and TSFX-compatible suppressor systems. If your suppressor is part of either of those mounting platforms, this adapter will interface with it. Always verify your suppressor's mounting spec before purchasing.
The .375 bore accommodates standard centerfire rifle calibers. It threads onto any barrel with 1/2x28 threads—the common thread pitch for rifles like .308 Winchester, 6.5 Creedmoor, .223 Remington, and similar cartridges. Do not use on larger-bore calibers without confirming bore diameter compatibility.
Yes. The nitride finish is applied specifically to handle the elevated temperatures and corrosive byproducts of suppressed fire. It resists fouling and corrosion better than bare steel, so it will remain functional and reliable with regular cleaning and maintenance.
Installation typically requires a standard armorer's wrench or similar tool to time the adapter correctly on your barrel threads. Exact installation procedures depend on your barrel and suppressor system—consult the documentation for your specific setup.
