If you are looking to build an all-purpose AR-15 that can be used for self-defense, range shooting, and competition, the Aero Precision 16" 5.56 M4E1 Enhanced Complete Upper Assembly is an excellent option. It includes a 16-inch barrel, modern handguard, high-quality receiver, and a low-profile gas system.
Made From High-Quality Material
The barrel is made from Mil-Spec CMV (Chrome Moly Vanadium) steel, which increases its strength, and high-temperature resistance as well. The barrel is also QPQ coated for longevity. The barrel has a 1/2"-28 thread pitch and comes with an A2 style flash hider.
The handguard on this upper assembly is an Aero Precision 15-Inch Gen 2 Enhanced M-LOK Handguard. It has M-LOK slots at 3, 6, and 9 o'clock, and a full-length Picatinny rail on top. The handguard is firmly mounted on the receiver with its built-in anti-rotation table and one-piece design and offers an excellent platform for mounting accessories and optics.
The receiver itself is forged from Aircraft grade aluminum and is very lightweight. It has a forward assist and a port door and features M4 feed ramps for better reliability. It is the perfect option for an all-purpose AR-15 build.
