Which ones fit your barrel and host?
Check in the BuilderThe Thunder Beast Silencer Summit fires every suppressor entered on the same gun, with the same equipment. SOCOM556-RC3 was measured in 1 test. Figures can only be compared with others from the same test, so each one links to everything else fired on that gun.

PEW Science · independent test
This suppressor has been independently sound-tested by PEW Science.
Manufacturer claim
- The SOCOM556-RC3 features a new internal baffle design engineered to maximize sound suppression while managing gas flow.
- The suppressor is part of SureFire's SOCOM series, which is designed to meet the demanding requirements of military and law enforcement users.
- The SOCOM556-RC3 is optimized for 5.56mm NATO platforms, consistent with the SOCOM556 product line heritage.
- The SOCOM556-RC3 is intended for use on military, law enforcement, and tactical applications with 5.56mm rifles.
Unattributed
- A typical unsuppressed 5.56mm rifle emits gases totaling 120 parts per million (ppm). The same rifle measures approximately 550 ppm when equipped with a SureFire SOCOM556-RC2, and approximately 200 ppm when equipped with a SOCOM556-RC3.
- Reduces back pressure by 60 percent over the SOCOM556-RC2, as measured using a US DOD-standard sealed test chamber with high-tech gas and particulate sensors.
- Muzzle flash levels are lower than the RC2, achieved after two additional years of development beyond the initial back pressure reduction milestone.
- Designed using exclusive parametric modeling and multi-variable aerospace software, totaling millions of CPU hours on supercomputers.

- From the lock ring forward, the SOCOM556-RC3 is precision-built entirely of mill-certified Inconel alloy, incorporating additive-manufactured components and CNC laser-welding.
- Features a novel internal baffle and front plate profile designed using computational fluid dynamics (CFD) software to deliver a 60% back pressure reduction compared to the RC2.
- Retains SureFire's patented Fast-Attach® system, ensuring backward compatibility with millions of SureFire SOCOM Fast-Attach muzzle devices currently in the field.
- Front plate geometry cools expended gases and minimizes turbulence, resulting in virtual elimination of muzzle flash without compromising durability.
- Proprietary baffle design expels the majority of gas forward out of the suppressor, significantly reducing gas traveling backward toward the shooter.
- Constructed from mill-certified Inconel alloy from the lock ring forward, using additive-manufactured (3D-printed) components and CNC laser-welding techniques.
- Incorporates additive-manufactured components as part of its advanced manufacturing process, contributing to its performance and durability claims.
- Delivers unprecedented durability, accuracy, and consistent repeatability regardless of attachment/removal cycles, enabled by Inconel alloy construction and CNC laser-welding.
- Reduced back pressure results in a longer lifespan for weapon components, improving reliability and reducing operator or unit/agency maintenance costs.
- Reduced back pressure notably decreases carbon buildup in the firearm, allowing it to remain cleaner for longer and further improving reliability.
- Compatible with existing SureFire SOCOM WARCOMP, flash hider, or muzzle brake muzzle devices — no replacement of existing Fast-Attach muzzle devices is required to run the RC3.
