Description
Big magnums hit hard on both ends, and the .338 Lapua Magnum is no exception. This Blackhawk muzzle brake, sold under the Bushnell banner, is built to take the sting out of that recoil so you can stay on glass and call your own shots. It threads on at 18×1.5mm and wears a black finish that blends right in on a long-range bolt gun.
What Sets the Wrath Muzzle Brake Apart
What makes this piece different from a plain brake is that it pulls double duty as the mounting system for the Blackhawk Wrath .338 LM suppressor. The exterior carries fast-pitch threads, so your can spins on and locks up in a matter of seconds with one hand. A locking collar at the base keeps everything snug through repeated strings of fire, which matters when you're feeding a rifle that generates the kind of pressure a .338 Lapua does.
Recoil Control and Real-World Use on the Wrath Brake
Used on its own as a brake, it does the job you'd expect from a device on a big magnum. It vents gas out to the sides to cut felt recoil and reduce muzzle rise, which translates into faster follow-ups and a lot less fatigue over a long day at the bench or in a match. Precision folks tend to appreciate being able to watch impacts through the recoil pulse rather than getting bounced off target. Anyone running a .338 knows the difference a good brake makes once you've shot a barked rifle bare.
Fit and Setup for the .338 LM Brake
This one is cut specifically for 18×1.5mm metric threads, so make sure your barrel matches before you order. If you already run the Wrath suppressor or plan to, picking up extra brakes for your other hosts lets you swap the can between rifles quickly. It's a straightforward install with the right wrench, and once it's timed and torqued, you're set.

Frequently Asked Questions
Does this Wrath muzzle brake work as a suppressor mount?
Yes. It's the muzzle device that mounts the Blackhawk Wrath .338 LM suppressor. The fast-pitch external threads let the can attach in seconds with one hand, and a locking collar keeps it secure through repeated firing.
What thread pitch does the .338 LM brake use?
This model is cut for 18×1.5mm metric threads, listed as 18Mx1.5. Check that your barrel is threaded to match before ordering, since the Wrath brake is also offered in other thread patterns like 3/4-24.
Can I use it just as a muzzle brake without the suppressor?
Absolutely. Run on its own it vents gas to the sides to cut felt recoil and reduce muzzle rise on a hard-kicking .338 Lapua. That makes follow-up shots faster and lets you spot your own impacts more easily.
Will this fit rifles other than the ones Blackhawk builds?
It fits any .338-class barrel threaded to 18×1.5mm. If you run the Wrath suppressor across multiple hosts, adding brakes to each rifle lets you swap the can between them quickly. Just confirm your muzzle threads match before installing.
