Will this work on a 38 special/357 magnum with 1/2x28 Expert Answer

The Ultradyne Lithium PCC Compensator Muzzle Brake, 9mm will not work with a 357 Magnum.

by Hunter, Gear Expert, February 13, 2023
I watched your installation video. It shows the technician turning the break to where it is "timed". What did he mean by that? Barrel length? Manufacturer Answer

Hi Bobby,
Thank you for reaching out! Great question! Timing a muzzle brake has nothing to do with barrel length — when the technician used the term timed, he was referring to the rotational position of the brake when it is fully tightened onto the barrel.

Does what it is supposed to do by ecovelli, Verified Owner, February 20, 2024
Fit and finish are fantastic, easy installation and looks better than OEM. Directs a lot of gasses up and out keeping muzzle rise to a minimum. If you need to shave a few tenths of a second of steel challenge or other competition, this is a great buy...

Excellent muzzle brake by SamSid, Verified Owner, April 3, 2026
Installed this in my S&W FPC. Installation with the timing nut is easy. Two 13/16” wrenches needed for both the muzzle device and the nut. Torqued to 25 lb-ft according to instructions. Makes for a very flat shooting experience. The PCC doesn’t have ...

Great job by Ultradyne by Fatman, Verified Owner, March 25, 2026
This works flawlessly. I especially love how easy it is to install and level to the gun while still having room to use your tools to tighten the nut. Have had zero baffle strikes with 700 rounds through it so far.

Shoots flat by Andy, Verified Owner, November 7, 2025
Put this on a Daniel Defense PCC with an FRT trigger and it shoots so incredibly flat. Perfect amount of compensation. Full mag dumps stay in the A Zone

Product Info for Ultradyne Lithium PCC Compensator Muzzle Brake, 9mm

Lithium allows a shooter to easily stay on target by featuring aggressive comp ports along with added recoil reduction. This results in faster follow-up shots with increased accuracy. The gases are strategically vented, so they do not obscure the sight path or travel back towards the shooter. Like all Ultradyne muzzle devices, a timing nut is included for easy installation.image
