The Luth-Ar Stripped A2 Upper is a no-frills, precision-machined receiver core built for shooters who want to assemble their own 5.56 NATO or .223 Remington rifle from the ground up. This stripped A2-style upper receiver gives you the classic carry handle profile with integrated rear sight cuts for windage and elevation adjustment—a time-tested design that's still the choice of builders who prefer iron sights or want to keep their optics setup flexible. Because it comes stripped (no BCG, charging handle, or furniture), you have complete control over the parts that go into your build and can tailor the rifle exactly to your needs.

Built from premium 7075-T6 aluminum forgings and finished with hard-coat anodizing, this upper receiver delivers the durability and precision you'd expect from a quality platform. The forged aluminum construction means it's lighter than some alternatives while maintaining the rigidity that matters downrange. You'll find the standard features that make an A2 upper reliable: shell deflector for reliable case ejection, forward assist housing for positive bolt closure, and provisions for an ejection port cover. The lack of M4-style cuts means this is purpose-built for the A2 profile—no compromise, no confusion about compatibility.

Whether you're rebuilding a classic rifle, assembling a lightweight recce gun, or putting together a dedicated varmint upper, this stripped receiver gives you a proven foundation without the cost and clutter of pre-assembled parts you might want to replace. Pick your own barrel, BCG, and charging handle, and build exactly what you need.

Frequently Asked Questions

What barrels and bolt carrier groups are compatible with this A2 upper receiver?

This A2 upper is designed to work with any 5.56 NATO or .223 Remington barrel assembly and standard AR bolt carrier group. Because there are no M4-style cuts, confirm that your barrel extension and gas tube are compatible with A2-profile uppers before ordering.

Is this upper receiver stripped, and what do I need to add?

Yes, this is a stripped receiver—it includes only the machined upper body. You'll need to source and install a barrel assembly, bolt carrier group, charging handle, and gas tube to complete a functioning upper receiver.

Can I use an optic mount or red dot with the A2 carry handle on this receiver?

The integrated A2 carry handle occupies the picatinny rail space above the receiver. If you prefer a flat-top optic mounting surface, this A2-profile upper is not the right choice; you would want a flat-top upper instead.

What finish is this upper receiver, and how durable is it?

The Luth-Ar A2 upper is hard-coat anodized for excellent corrosion resistance and durability. Hard-coat anodizing is thicker and harder than standard anodizing, making it well-suited for field use and long-term storage.
