Surefire Muzzle Brake for AR-15

FITS: M4, M16 and variants with 1/2-28 muzzle threads

MOUNTS: All SureFire SOCOM Series 5.56mm/.223 caliber sound suppressors

The SureFire SFMB-556-1/2-28 Muzzle Brake is engineered for AR-15, M4, and M16 platforms chambered in 5.56mm / .223, offering elite-level recoil control, faster target re-acquisition, and full suppressor compatibility. Designed for hard use in combat and precision applications, this advanced muzzle brake dramatically reduces muzzle rise and felt recoil—so your rifle tracks straight back, shot after shot. This brake also functions as a mounting adapter for SureFire SOCOM 5.56 Fast-Attach suppressors, including the SOCOM556-RC—the suppressor that topped U.S. Special Operations Command testing.

Built from US mill-certified, heat-treated stainless steel bar stock, the SFMB is precision machined with single-point cut threads for a flawless barrel interface. Its black Ionbond DLC coating resists corrosion and carbon buildup, even under extreme firing schedules and field conditions. The patented Impulse Diffusion design minimizes side blast and concussion, making it ideal for dynamic environments or team use. For those building short-barreled rifles (SBRs), blind pilot holes at the 6 o'clock position make pin-and-weld compliance simple. Pilot holes at the 3 and 9 o'clock positions also allow fine-tuning recoil impulse to match your ammo or shooting style.

Features:

• Caliber 5.56 mm (.223 caliber).
• Length 2.7 inches.
• Offset porting delivers greatly reduced recoil impulse and muzzle rise, so the weapon tracks straight back to keep you on target for faster shot-to-shot recovery.
• Multiple bearing surfaces for superior suppressor alignment.
• Precision machined from US mill-certified heat-treated stainless steel bar stock.
• High-precision single-point cut barrel threads for optimum thread interface.
• Inspected for all critical dimensions including concentricity and alignment.
• Pilot holes for tuning of muzzle brake and to pin-and-weld on short-barreled rifles.
• Black Ionbond DLC coating provides maximum protection against harsh environmental conditions and facilitates cleaning after extreme use.
• Serves as rock-solid mounting adapter for SureFire SOCOM Series sound suppressors.
• Labyrinth seals prevent carbon buildup on suppressor lock ring indexing system.
• Installation requires no permanent modifications for M4 / M16 / AR15 type weapons.
