Lantac 338 Arc 5/8-24 Plan B Longlantac Dragon Muzzle Brake

The Lantac Dragon muzzle brake in 338 Arc with 5/8-24 threading and Plan B hub mount is engineered to tame recoil and keep your shots on target, even in rapid-fire strings. Lantac's patented Short Energy Pulse system works by separating recoil impulses so they don't stack up and push you off-aim between rounds. Whether you're running precision rifle drills, testing a high-power build, or pushing the limits of your favorite magnum, this brake delivers the kind of recoil management that matters when accuracy counts.

Built to Lantac's quality standards, the Dragon brake muzzle rise reduction and controllability gains are measurable—especially noticeable under full-auto fire or rapid strings where muzzle climb traditionally breaks your sight picture. The Plan B hub mount system integrates with modern direct-thread suppressors and adapters, making this brake a versatile anchor point for a modular sound signature setup. A timing shim set is included so you can fine-tune barrel timing or suppress concentricity issues during installation.

The 338 Arc cartridge demands precision and discipline, and this brake respects that by letting you keep a repeatable sight picture shot to shot. If you're building a 338 Arc rifle for long-range hunting, PRS-style competition, or just want confidence in rapid follow-up accuracy, the Dragon brake's proven design does the heavy lifting on recoil so you don't have to.

Frequently Asked Questions

Will this muzzle brake work with my 338 Arc rifle?

Yes. The brake is chambered for 338 Arc and features 5/8-24 threading, which is the standard thread pitch for this cartridge. Confirm your barrel's thread pattern before ordering.

What is the Plan B hub mount?

The Plan B hub mount is Lantac's modern direct-thread design that allows compatibility with suppressor mounts, QD adapters, and other modular muzzle devices. It integrates easily into modern suppressor host systems.

Lantac's patented design separates successive recoil impulses so they don't overlap and compound, reducing muzzle climb and allowing you to stay on target during rapid or automatic fire. This gives you better shot-to-shot consistency.

What's included with this brake?

The brake ships with a timing shim set, which allows you to tune barrel timing or address minor concentricity issues during installation.
