Sharps Bros Heatseeker Chassis for Ruger American Ranch 450 Bushmaster, 14" Aluminum Handguard, Black

The Sharps Bros Heatseeker Chassis transforms your Ruger American Ranch rifle chambered in 450 Bushmaster into a modern, tactically-configured platform. Built from aluminum and finished in durable black Cerakote, this 14-inch handguard replaces the factory forend with a lightweight, rigid structure designed for shooters who want to modernize their rifle without a complete rebuild. Whether you're setting up a ranch rifle for predator control, hog hunting, or tactical training, the Heatseeker gives you a professional appearance and practical modularity at a fraction of the cost of a new rifle.

The chassis is engineered to work with your existing Ruger American Ranch action and feeds from box magazines—no modifications or gunsmithing required. The aluminum construction keeps weight minimal, and the M-LOK compatible mounting system on the forend lets you attach lights, lasers, vertical grips, and other accessories exactly where you need them. Black Cerakote finish resists wear and corrosion, making it practical for field use or range time.

If you're running a 450 Bushmaster for hunting or tactical applications, the Heatseeker chassis is a straightforward way to modernize ergonomics and add rail real estate without replacing your entire rifle. Installation is typically straightforward for anyone comfortable with basic rifle work, though a gunsmith can handle it if you prefer professional fitting.
