Details:
The Mercury .308 Muzzle Brake is designed to manage the heavier recoil impulse of large-frame rifles without turning each shot into a concussive experience. Its defining feature is a series of progressive 90-degree side ports that vent gas in controlled stages rather than all at once. By spreading the recoil impulse over time, the brake helps neutralize muzzle rise and keeps the rifle tracking flatter through the shot. The result is smoother recoil and more manageable follow-up shots, especially noticeable during rapid strings with .308-class cartridges.
Compact Performance Without Excess Bulk
Big rifles don’t need oversized muzzle devices to shoot well. The Mercury Muzzle Brake maintains a compact, lightweight profile that preserves the rifle’s balance and handling while still delivering meaningful recoil reduction. It’s well suited for precision-oriented builds, duty-style rifles, and practical .308 setups where control matters but excess weight at the muzzle does not.
Dynamount Ready for Barrel-Mounted Sights
The Mercury .308 is fully compatible with Dynamount barrel-mounted front sights. Mounting the sight directly to the barrel eliminates the potential point-of-impact shifts that can occur with handguard-mounted sights, particularly under recoil or when loading into barricades. The result is more consistent sight alignment and greater confidence during demanding shooting conditions.
Built for Pressure, Heat, and Long Service Life
Each Mercury brake is 100% CNC machined in the USA from 416 stainless steel and finished with a durable salt bath nitride treatment. This construction allows it to withstand the heat, pressure, and fouling common to .308 platforms while resisting corrosion over time. An included timing nut makes installation clean and straightforward, removing the need for shims or trial-and-error alignment.
For shooters who want effective recoil reduction on a .308 rifle without excessive blast or unnecessary bulk, the Mercury .308 Muzzle Brake delivers smooth, predictable performance in a durable, thoughtfully engineered package.
