SureFire flashlights are known around the world as the lighting system for any and every tactical scenario. In 1969 their original product line consisted of laser sighting systems for firearms. After many years of intense research and development, the SureFire Weapon Light was born and low light law enforcement & military operations changed forever. SureFire then went on to establish themselves as the leading manufacturer of rugged, powerful and compact illumination tools for tactical applications; from weapon-mounted lights and laser sights, shield lights, baton lights & hand-held lights powerful and bright enough to qualify as force-multiplier tools that could temporarily blind, unbalance, and disorient a threat.

The ability to adapt to constantly changing battlefield conditions is crucial to your team's rate of success. SureFire recognises your need for this level of versatility with the 660 Classic Universal WeaponLight , which is designed to mount directly to the barrel, suppressor, or under the front sight of your firearm. This modular light or laser mounting system provides unequalled flexibility that will meet or exceed your mission-specific/mission-critical requirements.

The 660 Classic Universal WeaponLight is powered by two 3-Volt lithium batteries, and produces a 65 lumen beam. Optional modules can be employed to convert the 660 Classic into a laser aiming device.

High Output

Optional P61 Bulb delivers 120 lumen tactical-level beam

Dual Mount Option

Optional A16 adapter enables dual light and laser mounting

Visible Or IR Laser Option

The 660 can be converted to a laser aiming/pointing device by installing the optional L72 ( 5mW ) visible laser module or the L75 IR laser ( 5mW ) module. ( Note: IR laser must not be operated with a constant-on switch )

Prefocused Beam

No need to twist the bezel to adjust the beam, it's already perfectly prefocused. Lamps and reflectors are individually mated and hand-adjusted to within .005" for optimum beam quality at all distances.

The SureFire Difference

SureFire strives to design and manufacture lights of ever-increasing brightness and quality while setting new standards for maximum power with minimal size. Three things characterise every product: compact size, extreme ruggedness, and a flawless high-output beam. Every SureFire illumination tool is guaranteed to produce a perfect centre spot of intense light surrounded by a smooth corona of softer light.

No Hassle Lifetime Warranty

Lamps will burn out, batteries will be used up, and switches for WeaponLights™ will eventually need to be replaced. Everything else is covered by their lifetime no-hassle guarantee; if it breaks, SureFire will fix it!* Made in the USA
