L3I Design Solutions

L3I Design Solutions manufactures precision rifle chassis, billet magazines, and competition shooting accessories designed by competitive shooters for competitive shooters. Every product is CNC-machined and assembled in the USA using premium materials like 6061 aluminum and 7075-T6 billet.
