The revolutionary SureFireA(R) WARCOMP-762-5/8-24 flash hider, which fits 7.62 (.308 caliber) rifles with 5/8-24 muzzle threads, is the world's most shootable flash hider. Its patent-pending design provides three valuable functions: It provides over 99% reduction in muzzle flash compared to a plain muzzle, which helps to conceal the shooter's location and preserve his dark-adapted vision. It virtually eliminates muzzle rise, which enhances monitoring target reaction and staying on target for faster follow-up shots. It serves as a rock-solid mounting adapter for all SureFireA(R) SOCOM Series 7.62 mm Fast-Attach suppressors, which share the same basic design as our SOCOM556-RC model, which placed first in the most extensive and rigorous suppressor testing ever conducted by US Special Operations Command. Precision machined from US Mill-certified heat-treated stainless steel bar stock including high-precision single-point cut threads for optimum thread interface the WARCOMP-762-5/8-24 features an Ionbond DLC coating to provide maximum protection under harsh environmental conditions and to facilitate cleaning even after extreme use. When used in conjunction with a SureFireA(R) SOCOM Series Fast-Attach suppressor, the WARCOMP provides multiple bearing surfaces to ensure superior suppressor alignment and prevent any ringing of tines inside the suppressor. A rear labyrinth seal mitigates gas leaking from the back of a suppressor, minimizes potential carbon buildup in the indexing system, and facilitates suppressor removal after extended firing. Every SureFireA(R) WarComp is individually inspected for concentricity and alignment.For rock-solid mounting of a SOCOM Series suppressor, unparalleled flash reduction, and minimizing muzzle rise, there's literally nothing like a SureFireA(R) WarComp the world's most shootable flash hider.
