Luth Ar 308 Upper Receiver$151.04
Availability: In Stock
Building an AR-15 from the ground up starts with a quality upper receiver, and the Luth-AR AR-15 stripped forged upper receiver gives you a mil-spec foundation built to last. Whether you're assembling a custom rifle for hunting, competition, or the range, this stripped upper provides the structural integrity and compatibility you need without the premium markup of complete assemblies. Machined from 7075-T6 aluminum—the same material spec used in aerospace and high-end firearms—this receiver is forged for strength, then hardcoat anodized to a durable black finish that resists wear and corrosion through years of field use.
The upper comes configured with an A3 flattop design and M4-type feed ramp geometry, ensuring reliable feeding across standard .223 Remington and 5.56 NATO ammunition. The integrated 12-position Picatinny rail gives you flexibility to mount optics, sights, or other accessories exactly where you want them. Practical touches like the shell deflector, forward assist housing, and pre-drilled ejection port cover save you time and guesswork during assembly—everything is ready to go once you add your barrel, bolt carrier group, and furniture.
For the builder who values precision without paying for unnecessary frills, this Luth-AR upper delivers mil-spec performance at a straightforward price point. The forged aluminum construction and hardcoat anodize mean you get a receiver that'll hold zero and handle real-world use without babying.
| Material | 7075-T6 aluminum forging |
| Finish | Hardcoat anodized black |
| Caliber Compatibility | .223 Remington / 5.56 NATO |
| Configuration | A3 flattop with M4-type feed ramp |
| Picatinny Rail | 12-position integrated rail |
| Receiver Type | Stripped upper (no barrel or bolt carrier group included) |
A stripped upper receiver requires a barrel, bolt carrier group, charging handle, and handguard or rail system to be complete and functional. You'll also need to pair it with a compatible lower receiver to build a complete rifle.
Yes. This is a mil-spec AR-15 upper with an M4-type feed ramp and standard dimensions, making it compatible with any mil-spec barrel, bolt carrier group, and lower receiver.
7075-T6 is an aerospace-grade aluminum alloy known for its strength-to-weight ratio and durability. It's harder and more rigid than lower-grade aluminum, making it ideal for precision firearms that need to hold zero and withstand repeated use.
Yes. The 12-position Picatinny rail is designed to accept standard Picatinny-mounted optics, flip-up sights, and other accessories.
