Jefferson, Georgia, Made in USA · Muzzle brakes · Self timing · Magnum calibers

• The Gen 4 Fat Bastard is a self timing brake for magnums like 300 Win Mag, with tunable top ports and a level line machined on the face.
• Self timing means the brake clocks itself on the threads, so you don't need shims or a crush washer.
• APA brakes are machined start to finish in its own shop.
