Traditional Aluminum STyles, made in the USA. Shiloh is available is 3 grades plus the new Alumabella Series. Alumabella features our new patent pending posiloc rail cover which snaps onto the rail to give you a totally stealth, screwless look. Sections are available in both 6' and 8' lengths. The Alumabella rail creates an I-beam which more than doubles the strenth of the rails.
