Features Lightweight aluminum construction Anodized black finish QD style fits over standard birdcage flash hiders Color: Tan The Eagle Force Auto Tracer is a full metal, ball bearing quick detach, equipped with a sensor that will trigger an illumination device to light up internally when a 6mm projectile is fired. Tracer units require that you pair them with glow-in-the-dark / tracer Airsoft BBs for full effect. Tracer rounds are easy to follow on a dark night and make target marking much easier. The Eagle Force tracer will also work with regular BBs as a mock silencer or barrel extension, enhancing the look of your gun. Designed to work with standard M4 / M16 birdcage flash hiders, the tracer is easily to install and remove on the fly. Compatibility: For use with standard M4-style "birdcage" flash hiders. May require modification for some brands and models. Dimensions: 195mm x 37mm (Recessed 40mm) Material: Anodized Aluminum Batteries: 4x AAA's (not included) Manufacturer: King Arms / Eagle Force 4
