Streamlight TLR-4G 160 Lumens Weapon Light & Green Laser with Rail Grip Clamp Mount - Black Anodized Polymer

The Streamlight TLR-4G is a compact rail-mounted weapon light and green laser built for shooters who need both illumination and aiming assistance on tight platforms. This tactical light pairs a 160-lumen C4 LED with an integrated 510–530nm green laser in a single, lightweight unit that mounts directly to your pistol or carbine's rail system. Whether you're running a home-defense pistol, competition gun, or low-light hunting setup, the TLR-4G delivers the brightness and targeting capability of a full-size light in a form factor that doesn't compromise concealment or handling.

The standout feature here is flexibility. A three-position mode selector lets you run the laser alone, the LED alone, or both together—giving you options depending on distance, lighting conditions, and your tactical preference. The green laser excels at longer ranges and in daylight conditions where a red laser would wash out, while the 160-lumen LED handles everything from close-quarters work to medium-distance target identification. The ambidextrous momentary/steady switch is positioned for intuitive operation without shifting your grip, and the one-handed snap-on rail clamp means you can attach or detach the light fast and safely, keeping your hands well clear of the muzzle.

Build quality is solid. The housing is impact-resistant engineering polymer with a durable anodized aluminum facecap, and the borofloat lens resists heat damage. The laser zero is held by windage and elevation screws in brass bushings, so once you dial it in, it stays put. The whole rig weighs just 2.81 ounces with battery and runs on a single CR2 lithium battery (included). It's rated IPX4 water-resistant, handles operating temperatures from –20°F to +120°F, and is serialized for tracking. Assembled in the USA with a limited lifetime warranty backing the investment.

Frequently Asked Questions

What weapons will the TLR-4G fit?

The TLR-4G mounts to any firearm with a Picatinny (MIL-STD-1913) rail via the included rail clamp. The mounting key kit accommodates a variety of weapons; note that H&K USP models do not include the key kit. Streamlight also offers versions specifically designed for H&K USP Compact and H&K USP Full Size frames if you need a tailored fit.

How long does the battery last?

Runtime depends on which mode you use. LED only runs approximately 1.75 hours, LED and laser together run about 1.25 hours, and laser-only mode runs roughly 4 hours. The light uses a single CR2 lithium battery, which is included.

Can I use just the laser, or just the light?

Yes. The three-position mode selector lets you choose laser only, LED only, or both together. This gives you tactical flexibility depending on distance, lighting, and your preference for the shot.

Is the green laser more visible than red?

Green lasers (510–530nm) offer higher visibility at longer ranges and in daylight conditions compared to red lasers, making the TLR-4G particularly useful for mid- and long-range target work where you need the aiming dot to cut through ambient light.
