An excellent choice for a new build, or upgrade for an existing AR15, Bravo Company's KeyMod Rail weighs a mere 5.2 ounces, a remarkable achievement for a 7" rail. Thanks to a proprietary alloy of aluminum and magnesium, it weighs about 30 to 40 percent less than aircraft aluminum but retains the same strength. It has a special finish originally developed for the aerospace industry that creates a ceramic-like surface with superior wear and corrosion resistance when compared to anodizing or even hard chrome.
