SureFire Picatinny rail forends replace your weapon's factory forend, providing multiple rails to mount accessories such as SureFire WeaponLights or laser sights. Precision machined from high-strength aluminum, that's Mil-Spec hard anodized, they're extremely tough, dissipate heat efficiently, and provide a rock-solid mounting platform. Our two-part Picatinny rail forends for AR-15 and AK-47 type weapons use integral tabs that lock the two halves together solidly. From SureFire, the tactical technology company®.
