Building a .308 AR platform rifle starts with a quality upper receiver, and the Luth-AR .308 stripped upper receiver delivers the precision machining and mil-spec durability you need for a solid foundation. This is raw material for builders who want to control every component of their build—no barrel, BCG, or handguard included, just the carefully engineered upper that ties everything together. Luth-AR's reputation for no-nonsense AR engineering goes back decades, and this .308 upper carries that same commitment to tight tolerances and reliable performance.

Machined from 7075-T6 aluminum forging, this upper combines strength with a weight profile suited to .308 platforms. The hardcoat anodized black finish is both durable and professional-looking, designed to handle field use and resist corrosion. Whether you're assembling a long-range hunting rifle, a precision target gun, or a versatile big-game platform, this stripped upper gives you the starting point to do it right.

A stripped upper means you're buying the receiver itself—no internals, no preassembled parts. That puts you in control of your build timeline and parts selection, from barrel profile and length to gas system and handguard. It's the smart choice if you already have components on hand or want to spec out exactly what goes into your rifle.
