Surefire 621LMG Mossberg 500 Shotgun Forend Weapon Light 6 V

SureFire Integrated Forend Shotgun WeaponLight - Momentary and Constant-On Switching for Mossberg 590/500 w/ 14 inch barrel is a replacement forend that includes a built-in six-volt tactical light and two separate switches integrated into the forend: a pressure sensitive activation pad for momentary light use, and a constant On/Off rocker switch. A P60 high output lamp assembly from Sure-Fire is standard, providing 65 lumens of light for one hour. The optional Surefire P61 ultra high output lamp assembly can also be installed, boosting output to 120 lumens for 20 minutes of runtime. SureFire shotgun replacement forends feature a shock-isolated bezel / lamp assembly and a machined barrier between the lamp and battery stick to prevent the battery stick from slamming into the rear of the lamp during recoil. Batteries within the battery stick are separated by a fiber washer and held within a plastic sleeve as further insurance against recoil-related failure.
