Sharps Bros Heatseeker Chassis for Ruger American Short Action, 14" Handguard, Aluminum, Black$455.95
Availability: In Stock
The Sharps Bros Heatseeker Chassis transforms your Ruger American Ranch short action rifle into a modern, tactical platform without breaking the bank. Built from solid 6061-T6 aluminum billet and weighing just 1 pound 3 ounces, this chassis system swaps in for your factory stock to give you AR-15 magwell compatibility, improved ergonomics, and a purpose-built setup for hunters and shooters who want to modernize a classic action. If you're running a Ranch model in .223, .300 Blackout, .350 Legend, 6.5 Grendel, or .450 Bushmaster and feeding it AR magazines, this is the direct-fit upgrade you've been looking for.
The Heatseeker chassis includes a 14-inch handguard machined from Sharps Bros' proprietary aluminum extrusion profile—a 10-ounce component designed to deliver a slim, secure grip with clean lines. The AR buffer interface keeps you compatible with standard mil-spec components, so upgrades and customization follow familiar paths. It's lightweight without feeling flimsy, rigid where it counts, and backed by the reputation of a builder trusted by precision rifle shooters and working hunters alike.
Whether you're customizing a Ranch rifle for varmint duty, precision rifle competition, or just want to modernize your bolt-gun ergonomics, the Heatseeker delivers real versatility at a price point that won't demand a second mortgage. Installation is straightforward on compatible models—no permanent modifications to your receiver needed.
