Sharps Bros now sells the Heatseeker chassis as an aftermarket option for bolt-action rifles. The 1-pound 3-ounce body is cut from a solid 6061-T6 aluminum block and pairs with a European walnut stock that includes an adjustable cheek piece, sling sockets, and a lower accessory rail.

A matching 14-inch, 10-ounce handguard uses a company-specific extrusion and receives the same matte black Cerakote coating as the chassis. Four-sided M-LOK slots plus two quick-detach fittings on each side support lights, bipods, and slings.

The Ruger American short-action model in .308-family cartridges accepts AICS magazines from Magpul or Accuracy International and can be fitted by the owner in roughly ten minutes using the supplied instructions.
