Streamlight TLR-4 Gun Light 170 Lumens Red Laser HK USP Compact

The Streamlight TLR-4 delivers tactical illumination and laser targeting in a compact package specifically engineered for the HK USP Compact. This weapon-mounted system combines 170 lumens of C4 LED white light with a red laser sight, providing shooters with enhanced target acquisition capabilities in low-light environments.

What Makes This Different

Unlike generic rail-mounted accessories, the TLR-4 features manufacturer-specific keys that ensure proper fit and function on the HK USP Compact's proprietary rail system. The integrated design eliminates the bulk of separate light and laser units while maintaining the pistol's balance and holster compatibility. Streamlight's C4 LED technology produces 170 lumens with a focused beam pattern that extends effective engagement range beyond standard pistol distances.

Key Features

• 170-lumen C4 LED white light with 1.5-hour runtime
• Class 3R red laser sight with <5mW output power
• Ambidextrous momentary and constant-on switching
• HK USP Compact-specific mounting key included
• Impact-resistant polymer construction with aluminum bezel
• IPX4 water-resistant rating for adverse conditions
• CR2 lithium battery power with 2-year shelf life

The TLR-4's dual-mode operation allows independent activation of light, laser, or both simultaneously through intuitive paddle switches accessible from either side of the frame. The system maintains zero through repeated mounting cycles, making it suitable for duty carry, home defense, and competitive shooting applications. Weather sealing protects internal components from moisture and debris during extended field use.
