Introducing the Heatseeker, an innovative and affordable chassis system designed to upgrade your bolt action rifle with enhanced versatility and a modern aesthetic. This lightweight chassis weighs just 1 lb, 3 oz and is precision machined from solid billet 6061-T6 aluminum. It features a 14 inches handguard cut from a unique Sharps Bros extrusion, all finished in a matte black cerakote for durability. The handguard boasts M-LOK slots on all four sides, accommodating attachments such as lights, bipods, night vision and ARCA rails. Each side includes two quick disconnect fittings for sling attachment convenience. The chassis utilizes a standard AR-15 grip interface, with options like our Brazilian cherry grip and handguard panel set (as shown in photos). Designed specifically for the box magazine fed Ruger American in .450 Bushmaster, Heatseeker includes an integrated AR buffer interface for easy customization with your preferred AR-15 type stock. Compatible with the Ruger American .450 Bushmaster 3-round polymer blue magazine, this chassis transforms the Ruger American Ranch into a high-performance platform without the need for gunsmithing. Installation is simplified with straightforward instructions, ensuring a seamless upgrade experience.
