Having a purpose-built weaponlight on your defensive AR-15 is a must-have accessory, since it allows for complete illumination and identification before engaging. The Cloud Defensive Optimized Weapon Light is specifically designed to provide enhanced illumination capabilities to firearm owners. One of the stand-out elements of the Cloud Defensive Optimized Weapon Light is the use of the company's patent-pending Lug-Lok innovation, which allows for quick-detach heads and tailcap switches for easy battery replacement. The design is also completely ambidextrous. 1250 lumen output Powered by a single 18650 battery User-programmable modes available Mfg: Cloud Defensive
