This is a Surefire Flash Hider known as the WARCOMP chambered in 7.62MM, model WARCOMP-762-5/8-24.
The revolutionary SureFire 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 SureFire SOCOM Series 7.62 mm Fast-Attach(R) suppressors. 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 SureFire 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. Every SureFire WarComp is individually inspected for concentricity and alignment.
