Ultradyne Mercury Muzzle Brake – .264 | 6.5mm | 5/8x24 Thread

Smooth. Balanced. Recoil-Taming Performance in a Precision Design.

The Ultradyne Mercury Muzzle Brake in .264 | 6.5mm (5/8x24 thread) is engineered for shooters who demand ultra-smooth recoil control, minimal muzzle rise, and maximum shooting comfort—all in a compact, precision-crafted package.

Featuring progressive 90° side ports, Mercury evenly disperses gasses in a sequence that flattens recoil, reduces shooter fatigue, and enables faster, more accurate follow-up shots. Perfectly suited for precision rifle builds, long-range platforms, or competition setups, it’s also Dynamount-compatible, allowing you to mount a front sight directly to the barrel for zero deflection and enhanced accuracy.

Machined in the USA from rugged 416 stainless steel and finished with an ultra-tough salt bath nitride coating, the Mercury brake delivers top-tier durability, performance, and aesthetics.
