Sharps Bros Heatseeker Features The Sharps Bros Heatseeker chassis is machined from billet 6061-T6 aluminum giving it a rigid high-strength structure that improves consistency over a traditional injection molded factory stock built for a .450 Bushmaster bolt action. At just 1 pound 3 ounces the chassis body adds minimal weight to the rifle while delivering the ergonomics and adjustability that chassis systems are known for. The design replaces the factory stock outright letting a shooter upgrade their rifle s handling and appearance without purchasing an entirely new action. A matte Black Cerakote finish covers both the chassis body and handguard giving the system a durable corrosion resistant exterior. A 14 inch handguard cut from an extrusion shape exclusive to Sharps Bros adds roughly 10 ounces to the overall package and includes M-LOK slots on all four sides for mounting a light bipod night vision device or an ARCA rail. Two quick disconnect fittings per side give the shooter multiple options for attaching a sling in whatever configuration suits their shooting style. Built specifically to fit box magazine fed .450 Bushmaster bolt action rifles the Heatseeker gives these rifles a modern chassis-style platform at an affordable price point. The Sharps Bros Heatseeker is for sale at GrabAGun for .450 Bushmaster rifle owners looking for an accessible chassis upgrade.
