Next Level Armament adapted its NLX-11 .450 Bushmaster brake to the .458 SOCOM by changing the thread to 5/8x24, the common .458 SOCOM muzzle thread. Body dimensions match: 2.5 inches long and 0.88 inches in diameter, nitride finished.
It is built to reduce the heavy recoil and muzzle jump of a big-bore AR-15 so follow-up shots on hogs and deer come faster. Although .308 barrels share the 5/8x24 thread, this brake's bore is sized for .458 bullets and belongs on a .458 SOCOM build.
