Aero Precision is one of the premier American manufactures of AR-15 parts. Their reputation for quality is second to none while still maintaining economical prices that make them the choice of many first time AR-15 owners. Aero Precision isn’t just a top rate manufacturer but an industry leader in the design of parts and accessories making the AR-15 an ever-evolving platform.

This complete M4E1 upper receiver is a ready addition to any high-quality AR-15 project. The M4E1 Threaded upper receiver features an enhanced forging that gives the upper receiver a “billet look”, and the Picatinny rail blends seamlessly with the ATLAS R-ONE handguard to produce a truly uninterrupted top rail. Additionally, the handguard includes QD sling sockets at the 3, 6 and 9 o’clock positions as well as a multitude of M-LOK slots for the optional addition of accessories. This complete upper does not include a bolt carrier group or charging handle, but once you’ve added those parts as well as a complete lower receiver, you’ll be ready to slap steel and punch through paper. Aero Precision are one of the premier names in AR-15 parts and components, and Aero’s complete uppers are yet another example of their dedication to quality.
