The Sharps Bros Overthrow is a stripped AR-15 lower receiver chambered for .223 Remington and 5.56 NATO, with a black hardcoat anodized finish. It has no sights or barrel, so it is the starting frame for a complete rifle. The supplier notes that it accepts standard AR-15 fire-control parts and works with a manual safety selector. The listing is for a new part in the lower receiver category.

Idaho builders often start from a lower like this and then add their own upper, barrel and trigger group. Because the stripped lower is itself a firearm under federal law, the transfer runs through a licensed dealer, and the buyer finishes the rifle afterward. Idaho's deer seasons depend on the game management unit, so check the Idaho Fish and Game rules for the rifle you end up building.
