Surefire WARCOMP Flash Hider / Suppressor Adapter for M4/16 Rifles and Variants 5.56 and 7.62


(9 customer reviews)

The revolutionary SureFire WARCOMP-556-1/2-28 and WARCOMP-762-5/8-24 flash hider, which fits M4 / M16 weapons and variants with ½-28 muzzle threads, or 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 of target reaction and staying on target for faster follow-up shots.

It serves as a rock-solid mounting adapter for all SureFire SOCOM Series 5.56mm and 7.62 mm Fast-Attach® suppressors, including 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-556-1/2-28 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, and facilitates suppressor removal after extended firing. Every SureFire 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 SureFire WarComp—the world’s most shootable flash hider. FITS: M4, M16 and variants with ½-28 muzzle threads MOUNTS: All SureFire SOCOM Series 5.56mm /.223 caliber sound suppressors or 7.62 mm (.308 caliber) rifles with 5/8-24 muzzle threads

NOTE: SureFire SOCOM Series Fast-Attach sound suppressors and current-model WarComps, muzzle brake and flash hider adapters are NOT compatible with previous (non-SOCOM) SureFire Fast-Attach sound suppressors, muzzle brakes, or flash hiders.

    Excellent muzzle brake – especially wanted it for the Fast-Attach platform which is compatible with both their suppressors and blast diffuser

    Best place to shop online. Quick and fast. Got this surefire for latest build. Did not disappoint. Great device.

  3. Jake Ansbach (verified owner)

    Jumped on a couple as soon as they came in stock, along with a warden. Both work great. Great pricing and crazy fast shipping as always.

    Bought this muzzle device in the summer and its performance did not disappoint. Typical well made SureFire product. So bought another one from Big Tex for a new build. Also, love ordering from the Big Tex team. CS is spot on and send out products very quick with some goodies.
