Muzzle Brake for Dragon® Dead Air® KEYMO™ Suppressor / .300 BLK Lantac®

The Dragon® DGN300B-WM combines a high-performance muzzle brake with the Dead Air® KeyMo™ quick-attach system for .300 BLK rifles. It smooths firearm operation, accelerates target re-acquisition, and prepares the barrel for suppressor use—without modifications or compromises.

Stability at Speed

Directional gas channels vent pressure away from the bore axis, minimizing muzzle climb and drift. The rifle stays firmly shouldered, allowing shooters to maintain a dynamic rate of fire while keeping accuracy intact.

Suppressor-Ready in Seconds

The WM version integrates the Dead Air® KeyMo™ system, enabling rapid attachment of the Wolfman™ suppressor with a simple slide-and-twist action. This modularity makes switching from standard to suppressed configurations fast and effortless.

Robust Stainless Steel Construction

CNC-machined from a single billet of stainless steel, the Dragon^® resists heat, abrasion, and carbon buildup. The protective finish reduces fouling adhesion and extends service life, even under heavy use.

Optimized for .300 BLK

Designed for both supersonic and subsonic .300 AAC Blackout loads, the DGN300B-WM maintains consistent brake effectiveness when paired with a suppressor, without compromising firearm reliability.

Made in the USA

Manufactured on advanced CNC machinery in the United States, each Dragon® undergoes strict quality control. Lantac’s expertise in both suppressed and unsuppressed platforms ensures proven durability and performance.
