SureFire SF3P-556-1/2-28 Flash Hider Suppressor Mount 5.56 NATO

The SureFire SF3P-556-1/2-28 flash hider delivers dual functionality as both an effective muzzle device and quick-attach suppressor mount. This precision-engineered component eliminates muzzle flash while providing a rock-solid mounting platform for SureFire SOCOM series suppressors.

What Makes This Different

Unlike standard flash hiders that only reduce muzzle signature, the SF3P incorporates SureFire's proven quick-attach system with precise indexing. The three-prong design provides 99% flash elimination compared to 85-90% from traditional A2-style devices. Internal threading and indexing system maintains zero when transitioning between suppressed and unsuppressed configurations.

Key Features

• Quick-attach mount compatible with SureFire SOCOM 556-RC2 and 556-Mini2 suppressors
• Three-prong closed-tine design for maximum flash suppression
• Precision-indexed mounting system maintains point of impact
• 1/2"-28 TPI threading fits standard 5.56/.223 barrels
• Stainless steel construction with black nitride finish
• Wrench flats for secure installation without thread damage
• Crush washer included for proper timing and installation

Field testing demonstrates consistent flash reduction across various ammunition types and barrel lengths. The closed-tine configuration prevents debris accumulation while maintaining structural integrity under rapid-fire conditions. Law enforcement agencies report reliable suppressor attachment/detachment after thousands of rounds without loosening or timing shifts.
