The AERO PRECISION M4E1-T 5.56 16in Complete Upper Receiver with 15" M-LOK Atlas Handguard 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 without the billet price. An ATLAS S-ONE handguard features a lightweight design with Picatinny sections at the front and back only, and indexing grooves along the top aid in a more positive grip.
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.
