The SureFire 628LMF-B Forend Weaponlight delivers a powerful 1,000 lumens of bright white LED illumination to enhance low-light operations on your Heckler & Koch MP5, HK53, or HK94 carbine, replacing the original forend with a virtually indestructible emitter focused by a TIR lens for a beam optimized to close- to medium-range engagement. This polymer aluminum construction keeps weight at 17.6 ounces while providing rugged durability, and its compact 9.48-inch length ensures a balanced, secure grip during fast targeting. Power is supplied by two CR123A batteries, offering a practical runtime of 1.25 hours for extended missions, and the ergonomic control scheme features a right-side momentary-on pressure-pad switch paired with a left-side rocker-type constant-on switch, enabling intuitive operation without compromising weapon handling. The ergonomic, purpose-built design supports seamless integration with tactical setups, delivering reliable illumination to identify and engage targets confidently in challenging lighting conditions. With the SureFire 628LMF-B Forend Weaponlight, you gain high-performance output, durable construction, and practical control features that enhance your shooting experience and overall situational awareness in demanding environments.
