The SureFire SF3P5561228 SOCOM Series suppressor adapter and flash hider is designed for M4, M16, and compatible rifles with 1/2-28 muzzle threads. Built for 5.56mm platforms, it helps reduce muzzle flash while providing a secure mounting interface for SureFire SOCOM Series 5.56mm Fast-Attach suppressors. Its compact design supports reliable handling and quick suppressor installation for professional, duty, training, and recreational applications.
The patented Impulse Diffusion design helps reduce recoil impulse, muzzle rise, side blast, and rear-directed concussion. By helping the firearm track more naturally during rapid fire, the SF3P5561228 can support faster shot-to-shot recovery and improved control. The adapter is precision machined from U.S. mill-certified, heat-treated stainless steel bar stock and features high-precision, single-point-cut threads for a consistent and durable thread interface.
A black Ionbond DLC-style protective finish helps resist wear and corrosion in demanding environments while simplifying cleaning after extended use. The 1/2-28 thread pattern is intended for compatible 5.56mm barrels, and professional installation should be performed by a qualified gunsmith to verify proper alignment and compatibility with the firearm and suppressor system. Always follow applicable laws, manufacturer instructions, and safe firearm-handling practices.
