KAK PLAN B RADIAL BRAKE 5/8X24 .375"

The KAK Plan B Radial Brake is a compact muzzle device designed for shooters running 5/8x24 threaded barrels in .375 caliber. Built from 17-4 stainless steel with a nitride finish, this muzzle brake combines durability with a no-fuss installation process—no timing required, so you can have it on your rifle in minutes without the guesswork that comes with many other brakes.

KAK Industry manufactures this brake entirely in-house, controlling every step of the machining process for consistent quality. The radial design disperses recoil impulse outward from the bore, helping manage felt recoil and muzzle rise without the linear shove of simpler designs. At just 1.7 ounces, it adds minimal weight to your barrel while keeping your overall package trim and handy.

The rear of the brake features milled flats sized for an 13/16-inch wrench, making installation straightforward whether you're doing it yourself or at a gunsmith. The compact 1.850-inch length keeps the profile low, so you won't sacrifice sight radius or add bulk if you're running optics or iron sights. This is a no-nonsense muzzle brake for rifle builders and hunters who want effective recoil management in a hard-use platform.

Frequently Asked Questions

What barrels does this muzzle brake fit?

The KAK Plan B is threaded 5/8x24, which is the standard thread pitch for .375 caliber magnum rifle barrels. Verify your barrel's thread pattern before ordering.

Do I need to time this brake?

No. The Plan B threads on without timing, so there's no need to adjust it to a specific rotational position. Just thread it on, snug it down with the rear wrench flats, and you're ready to go.

What's the advantage of a radial brake design?

Radial designs channel gas outward from the centerline of the bore rather than straight back or to the sides. This helps reduce both recoil impulse and muzzle rise, making it easier to stay on target during follow-up shots without generating the harsh side-blast of some linear designs.

How much does this brake weigh?

The KAK Plan B weighs 1.7 ounces, keeping your barrel light and balanced while still delivering effective recoil management.
