AeroPrecision
The Aero Precision 5.56 assembled upper receiver with no auto sear cut is built for shooters in jurisdictions where standard AR-15 uppers aren't legal to own. This fully assembled upper comes ready to pair with a compatible lower receiver, giving you a complete, regulation-compliant rifle without the legal complications that can come with certain component configurations. Forged from 7075-T6 aluminum and finished in black, it delivers the durability and precision Aero is known for while meeting the specific requirements of European and other restricted markets.
This upper is chambered in 5.56 NATO and built to the same performance standards as any Aero upper you'd run downrange. You get M4-style feedramps for reliable feeding, an ejection-port cover to keep debris out, and a forward assist for manual bolt closure if needed. The takedown pin holes are machined to .250-inch spec, ensuring a solid, repeatable fit with your lower receiver. Best of all, it ships completely assembled—no gunsmith work required.
Whether you're building a rifle in a region with strict component restrictions or you simply need a no-compromise upper that checks all the boxes legally, this Aero upper delivers the fit, finish, and function that serious AR builders expect. Pair it with a compliant lower and you're ready to shoot.
