Primary Weapons Systems
The Advanced Technology .308 Shark Muzzle Brake is a purpose-built recoil management solution for .308 Winchester rifles and similar caliber platforms. Designed with the shooter in mind—whether you're behind a precision rifle at distance, running rapid fire drills, or hunting—this muzzle brake reduces felt recoil and muzzle rise to help you stay on target and shoot faster. The Shark model uses advanced porting geometry to redirect gas efficiently without sacrificing durability or long-term reliability.
Built to ATI Outdoors' precision manufacturing standards, this brake features a 5/8x24 threaded interface, making it compatible with any .308-caliber barrel with that specification. The included crush washer ensures proper timing and a repeatable, secure installation—no special tools or gunsmithing required. Finished in hard-wearing black, it's built to handle the wear and tear of serious shooting.
If you're upgrading a .308 rifle to reduce recoil and improve shooter control, or building a new precision platform from the ground up, the Shark brake delivers the performance and reliability you'd expect from a manufacturer focused on quality components and meticulous engineering.

The 5/8x24 thread pattern is the standard for .308 Winchester barrels. This brake will fit any .308 rifle with a barrel threaded 5/8x24. If you're unsure whether your barrel is threaded, or what the thread pitch is, confirm before ordering.
The brake ships with a crush washer, which is installed between the brake and the barrel to ensure proper timing and a secure fit.
Installation is straightforward for anyone comfortable handling a rifle. The crush washer and threaded interface make it a simple hand-tight fit—no special tools required. If you're not confident, any gunsmith can install it in minutes.
The Advanced Technology Shark design uses ported gas redirection to manage recoil and muzzle rise effectively. Actual recoil reduction varies based on your rifle's caliber, barrel length, and ammunition, so we recommend checking user reviews or consulting ballistics resources specific to .308 performance.
