Details:

If you’ve spent time messing with shims, alignment, or loose muzzle devices while trying to mount a suppressor, you know how frustrating it can get. The Kaw Valley Precision Plan B Taper Mount Brake cuts out the hassle with a smart, purpose-built design made for shooters who want a clean, reliable interface—no fine-tuning required.

Built for Plan B Suppressor Systems

This Plan B muzzle device isn’t a “universal” muzzle device that sort-of fits. It’s specifically machined for use with Plan B-style suppressor mounts—like the Rearden Atlas, Diligent Defense Zilch, and similar taper-threaded models. The taper and thread combo ensures a repeatable, rock-solid fit that holds tight through long shooting sessions and high round counts.

No Timing Needed—No Shims, No Fuss

One of the standout features here is how simple it is to install. You don’t need to time this brake to get it aligned—just thread it on, torque it down with a wrench using the built-in flats, and you’re done. No messing with shims, washers, or trial-and-error alignment. It’s the kind of install that takes minutes and stays tight.

Tough Build, Minimal Footprint

Made from heat-treated 17-4 stainless steel and QPQ nitrided for added surface hardness, this brake is built to handle abuse from suppressor use—heat, carbon, pressure, and all. The finish also helps seal gas better inside your suppressor, keeping fouling down and performance up over time. Despite that durability, it stays compact—only 1.27 inches long and about 1.4 to 1.7 ounces depending on the thread pitch.

If you're looking for a no-nonsense, Plan B muzzle device that installs easily, holds firm, and doesn’t add unnecessary bulk or complexity to your setup, the KVP Plan B Taper Mount Muzzle Brake checks all the right boxes. It's a smart choice for suppressor users who value function and fit over gimmicks.
