When it comes to starting a new AR-15 build, the hardest part is trying to decide which components to use. If you are looking to build a high-quality AR, Luth components are some of the best options to choose from and this stripped upper receiver is a step in the right direction. It is forged from 7075-T6 aluminum and hardcoat anodized for a durable, scratch resistant coating and comes with all the standard features of a Mil-Spec upper receiver. It has an A3 flat top design, so you can easily attach optics, scopes, red dot sights, or buis so you can be ready for any situation. The 12 position picatinny rail also features T-marks so you can remember your optics position when removing it for storage or maintenance without losing zero. The shell deflector and forward assist housing are precision machined and it is ready to accept a standard dust cover. The M4 style feed ramps aid in reliably feeding a wide variety of .223 Rem and 5.56 NATO ammo so your carbine or rifle will run flawlessly. Combine this upper with any Mil-Spec lower receiver and get your build started today.

Great for a Builder!

Great upper receiver. If you are looking for a cheap decent receiver do not hesitate!

Great quality, precise machining.

Better quality than most uppers. Luth is known for its quality precision machining.

Out of Spec


This receiver incorrectly clocks the cam pin forcing the bolt to be rotated slightly so that it won't naturally permit the bolt to enter the star chamber due to incorrect clocking. I bought TWO and ended up returning them to Luth and they ended up keeping the receivers and my money. So it is out of spec and Luth's customer service is abysmal.
