SureFire Flash Hider / Suppressor Adapter for M240 Machine Guns - SF3P-762MG-M240

The advanced SureFire SF3P-762MG-M240 three-prong flash hider, which fits the M240 machine gun, features a patent-pending design that greatly reduces muzzle flash-typically greater than 99%-when compared with a plain muzzle. Boasting robust tines built to withstand the rigors of combat, the SF3P-762MG-M240 also serves as a rock-solid mounting adapter for SureFire SOCOM762-MG Fast-Attach suppressor, the SOCOM762-RC model having recently won the Mk13 Mod 1 sniper rifle contract award with the US Special Operations Command in the most extensive and rigorous suppressor testing ever conducted.

Precision machined from US mill-certified heat-treated stainless steel bar stock-and including high-precision single-point cut threads for optimum thread interface-the SF3P-762MG-M240 flash hider is given a black 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 SOCOM762-MG suppressor, the patent-pending design of the SF3P-762MG-M240 provides multiple bearing surfaces to ensure superior suppressor alignment and to prevent the audible ringing of tines inside the suppressor. A rear labyrinth seal minimizes potential carbon buildup in the indexing system and facilitates suppressor removal after extended firing.

SureFire flash hiders are individually inspected for concentricity and alignment and are covered by SureFire's No-Hassle Guarantee.
