SureFire 328LMF-B Dedicated Forend WeaponLight for H&K MP5, HK53 & HK94 The SureFire 328LMF-B is a purpose-built dedicated forend WeaponLight engineered to replace the original forend of your Heckler & Koch MP5 submachine gun, HK53 rifle, or HK94 carbine. Designed for professional operators and serious tacticians, this drop-in replacement integrates seamlessly with your firearm while delivering 500 lumens of high-intensity white light through a virtually indestructible LED emitter focused by a precision TIR lens. The optimized beam pattern is tailored for close- to medium-range applications, providing a decisive advantage in any low-light tactical situation. Powered by a single 123A lithium battery, the 328LMF-B delivers a full hour of continuous runtime with a beam reaching up to 175 meters. Its ergonomic dual-switch system features a momentary-on pressure-pad integrated into the right side of the forend and a rocker-type constant-on switch on the left side, allowing seamless light control without breaking your normal firing grip. A hard-anodized aluminum bezel, tempered glass window, and O-ring seals deliver exceptional durability and weather resistance in demanding environments.
